Hi,
 
I've again encountered the problem of FreeBSD 7 not wanting to boot on a
HP server. The last time was early in 7.x development on a HP blade
(2xdual-core Opteron), without any solution (reported on this list about
a year ago). This time it's on a ML 350 G5 machine, with a quad-core Xeon.
 
The problem is very hard to diagnose - the entire machine locks up
during pci bus/device detection - the kernel debugger doesn't work, the
keyboard lights (PS/2 keyboard) don't work, it's completely frozen.
 
This is on both i386 and AMD64 kernels.
 
The machine freezes after detecting pcib6. The working 6.x kernel
detects upto pcib16, and the first device detected after pcib6 is the
CISS controller, so maybe it's the controller driver, but the first
machine (the blade) didn't have CISS controllers.
 
Any ideas?
