At least 3 servers:
ASUS P4T-E and P4S-533 m/b
P4 1.6Ghz and 1.8 Ghz CPU
512Mb memory
IDE disks

>Description:
These servers began experiencing hard hangs (even DDB key sequence does
not work) since 4.6. It happens on at least 3 different servers, all
with simple configuration (3COM 3C905C only non on-board adapter, USB not used,
parallel, serial ports not used, text mode console only, no X).
Servers have moderate to high load (busy web mail server, MRTG server).
Hang frequence is from 2/week to 2/day.
Absolutely nothing of interest in any log file.
Disabling dma (hw.ata.ata_dma="0" in /boot/loader.conf) makes hangs happen
less often (0.5/week) but does not make them disappear.
CVSup to 4.7-RC as of 18-Sep-2002 didn't fix problem.
4.7-RELEASE to be tried.
Downgrading one of the servers to 4.5-RELEASE has made it stable.

>How-To-Repeat:
Nothing special, just normal server operation. Unfortunately no way to
cause the hangs.
>Fix:
Downgrade to 4.5-RELEASE

 Boxes upgraded to 4.7-RELEASE: same.
 They hang a couple of times a week with DMA on and haven't hung yet with 
 DMA disabled (5 days up).
 COM, LPT ports and USB disabled in BIOS, usbd disabled in rc.conf to 
 avoid any IRQ sharing.
 One of the boxes will be migrated to Linux (sigh) to rule out h/w problems.

 Latest Asus BIOS flashed on one of the boxes: seemed to help a bit (9 days 
 up with DMA on)
 One of the boxes migrated to Linux (kernel 2.4.20): been rock solid for 25 
 days.
 Huess that rules out a h/w related problem.
