(probe23:arcmsr0:0:16:0): inquiry data fails comparison at DV1 step
run_interrupt_driven_hooks: still waiting after 60 seconds for xpt_config
From here on it hangs and repeats the last message with some sort of
exponential backoff. Ctrl-Alt-Del to reboot doesn't work but ScrollLock
does. Hard reset is required to reboot.
Booting the old 6.4 kernel works and the system comes up again with full
access to the RAID array.
Any help appreciated.
I'll try to reproduce this locally. There have been sporadic reports of
the "fails comparison" problem, but none as fatal as this. Is it
possible to compile your kernel with CAMDEBUG and
CAM_DEBUG_FLAGS=CAM_DEBUG_INFO?
CAMDEBUG doesn't give any output.
As it turns out the hang seems to be related to an interrupt routing
problem somehow. I did an BIOS upgrade and BIOS settings factory reset.
The mainboard is an ASUS M2N32 WS Professional with an Athlon64 X2 4800+.
Enabling all on-board devices including ATA and various SATA controllers
together with "PnP OS" set to yes fixed the hand and allowed FreeBSD 7 to
boot sucessfully. Why 6.4 doesn't stumble I don't know.
The "(probe23:arcmsr0:0:16:0): inquiry data fails comparison at DV1 step"
line is still there. Fortunately the boot process simply continues from
there without further trouble.
If there are any other CAM debug options or patches you want me to try I
can do that. The system is only in partial production and I'm allowed to
reboot it during workhours.
