>Description:
When booting from the install CD, the kernel panics with: 

panic: No BIOS smap info from loader
Uptime 1s

Irrespective of options (safe mode, single user, acpi disabled/enabled), (w) or w/out USB keyboard/mouse (PS/2 tried just in case), the kernel panics after the menu screen.

The machine is a HP dc5750 SFF with ATI X-Press 1150 chipset, 2GB DDR2 RAM (more details, of course in the "lspci -vxxx" output farther down.).  The BIOS is the newest from April 7, 2007 (2.13 Rev. A)

amd64 install cds (5.5, 6.1, 6,2 and all current snapshots from Sept.2006 to April 2007 tested with identical results.

The output of a rudimentary trace ((w) "boot" command as well)after escaping to the loader prompt is:

OK boot -v
GDB: no debug ports present
KDB: debugger backends: ddb
KDB: current backend: ddb
panic: No BIOS smap info from loader

KDB: enter: panic

Here is the output of "lscpi -vxxx" as "root" from a GentooLinux system:

Date: Mon, 21 May 2007 15:38:41 +0200

 This problem hit FreeBSD-i836 on the HP dc5750 as well.
 
 The 7.0-CURRENT snapshot from May 10th will only find 64 MB out of 1 GB
 installed. The loader print "BIOS 639/784064 kB" while the Kernel print
 "real memory = 67108864 (64 MB)". Asking the loader about the SMAP will
 print an empty line.
 
 This is the same with an older 6.2-STABLE. A more recent 6.2-STABLE of May
 18th prints the same in the loader, while the kernel print "real memory =
 1048576000 (1000 MB)", but the kernel fails to mount the root filesystem.
 Either automatically or manually provided.
 
 I think the cause for that is the on-board video-adapter which uses the
 system RAM. If I reduce the amount of usable memory by
 "hw.physmem=803561472" (a value detected by NetBSD on the same machine)
 in /boot/loader.conf the kernel will boot without a problem.
 
 Some remote kernel debugging sessions showed that in the function getmemsize()
 in /sys/i386/i386/machdep.c the kernel failed to get the memory map with
 INT 15:E820 and finally uses the RTC value for extended memory.
 
 The machine uses the newest system BIOS 786E3 v02.22.

 Meanwhile I tried the two oldest BIOS for this machine available from HP.
 Without any success. So, if the problem exists in the BIOS it's there
 at least since version 1.04 revision A.
 
 I also tried the old 4.11 FreeBSD/i386 ISO from the archive. It failed
 to detect the right amount of memory as well. So, the problem has nothing
 to with changes in newer versions of FreeBSD.
 
 A NetBSD 3.1 Generic MP AMD64 from Oct, 30 2006 detects 894 MB of total
 memory.
 
 Assuming that the loader is an simpler environment than the kernel, I have
 tried some modifications in different files (btx.S, btxldr.S, biosmem.c,
 biossmap.c and even biosdisk.c). Either without any success to get an
 successful SMAP call or even crash the loader.
 
 I found, that the loader calls BIOS int 0x15 function 0xe820, which fails,
 than int 0x12 and int 0x15 function 0xe801, both successfully.
 The kernel calls int 0x12 successfully, after that int 0x15 function 0xe820,
 which fails, then int 0x15 function 0xe801, which fails also, and then uses
 the rtc value.
 
 It is interesting that the int 0x15 function 0xe801 call, which succeeded
 in the loader, fails when called by the kernel. 
 
 A Linux kernel 2.6.19-gentoo-r5 will boot up fine. Even with showing the
 smap information and access to the ACPI. A recent FreeBSD 6.2-STABLE will
 crash in madt_probe() if tried to boot with ACPI enabled. It is the same
 with a CURRENT dating from 2007-05-29.
 
 I have also tried the Linux-ready firmware developer kit release 2 from
 www.linuxfirmwarekit.org. While booting, it shows the int 0x15 function
 0xe820 calls and results. In total it detects 0 MB highmem and 894 MB
 lowmem, which is the same amount as the NetBSD above. It also shows severeal
 failures and and warnings, but has access to the ACPI tables without crashing.

 There is some very little success. Using hint.apic.0.disabled=1 mentioned
 in the bugs section of acpi(4) let a CURRENT FreeBSD/i386 kernel boot
 with acpi enabled. There are now some warning messages regarding
 interrupts and failed memory allocations from the kernel but the power
 button works as expected now.
 
 To disable HPET in the BIOS will fix a hangup while configuring the
 bge(4) interface by dhclient(8).

 Hi,
 
 I've tried applying this hint (disabling apic) and defining the maxmem from
 the bootload prompt, but unfortunately, it doesn't boot up at all. The
 kernel still panics as described originally.
 
 Ralf: Are you actually running some sort of FreeBSD on the box already? We
 seem to have similar boxes with the same BIOS revision...

 I have just verified this with the 7.0-CURRENT-200706-amd64-disc1.iso
 version and you are right. Can you try a i386 version please?
 I know this is not the right categorie (amd64 vs i386) but this was the
 only thread I found discussing FreeBSD on the HP dc5750.
 I don't think this is problem is related to i386 or am64. I think it's
 more related to the BIOS and the different ways FreeBSD, NetBSD and
 Linux are calling the BIOS.

 I can build the world and a CURRENT kernel on the machine as well as
 install and run them. The machine is also able to use our diskless boot
 environment with some minor extensions in /boot/beastie.4th.
 
 We can not get full control over the ATI SB600 HDA controller. There is
 no output on the rear plug and the internal speaker volume is the same
 as the front headphone plug. Linux distinguishes between internal speaker
 and headphone, but there is no output at the rear plug as well.
 
 USB mouse and keyboard are detected and functioning. But there is a
 problem with USB sticks. Depending on the manufacturer (I tried 3 different)
 the stick is never detected as umass(4) device or there will be umass
 I/O errors. In any case the operation system will slow down until it is
 almoust not responding to keyboard (PS2 or USB) activity.
 
 Best regards, Ralf

 Hi,
 
 I've tested this on i386 cds as well (up to this month's
 6.2-Stable/7.0-Current)
 without noticing any differences.

 That's interesting. I have just used the 6.2-STABLE-200704 from the
 6.2-STABLE-200704-i386-disc1.iso snapshot, escaped to the loader prompt
 used "set hint.apic.0.disabled=1", "set hw.physmem=3219454976" (for 4 GB
 RAM) and boot up fine. Especially without a kernel crash. The BIOS
 version is 78E3 v02.25. There is no additional hardware added.
 For 1 GB RAM I had to use "set hw.physmem=803561472".
 
 Best regards, Ralf

 Hi,
 
 very interesting phenomena. With the Bios Rev. 2.25 I am now able to
 boot 6.2-STABLE-200706-bootonly for i386 w/out acpi, but not amd64 (with
 any options enabled/disabled). With the previous Bios version 2.22, also
 mentioned in the bugreport, this was not possible.
 
 With this configuration, I am able to install 6.2-RELEASE (with the
 requisite bge problems...).

 Hi,
 
 as Ralf also said, Linux can read the memory map from the BIOS.
 
 Here's the output from my current system:

 6-Stable can only see 64MB of this by default. With ACPI enabled, the
 kernel panics, just like with the previously mentioned boot cds.
