FreeBSD Blade 5.2.1-RC FreeBSD 5.2.1-RC #3: Thu Feb  5 13:30:14 CET 2004     root@Blade:/usr/src/sys/sparc64/compile/BLADE  sparc64

>Description:
This is a request to append a note to the documentation for sparc64, and a
way to get the solution into Google in any case.

We had installed 5.2-RELEASE on a Blade 150. it would work okay for a while,
but would reliably die during a cvsup with a

IOMMU fault at virtual address 0xC3000000                                       
Uncorrectable DMA error AFAR 0x696000 AFSR 0x210000ff000000000

in the end the solution turned out to be to unplug the USB keyboard. I had
found one message in the archives indicating the Blade150 needed to be
installed without the keyboard because it wasn't supported at all, but this
appeared not to apply: the machine installed fine and works for a while
before panicing, always under network load. But, as it turned out, that was it.


>How-To-Repeat:

>Fix:

Add a note to the sparc64 documentation that you really shouldn't have the
keyboard plugged in a Blade150 even if it appears to work fine at first sight.

 Hi, 
 
 Can you try with a more recent version of FreeBSD (as 5.3 is about to be
 released) and report if this is still a problem?  If it is, this PR may
 be better filed in the Sparc64 category as a bug to fix rather than
 something to document.
