Hello,
I am having the same exact problem you were having using the same
device. I started receiving this error on FBSD7-RELEASE and thought it
was specific to that version. Naturally I upgraded to FBSD7-Stable as
of today (9/25/2008), but still haven't been able to resolve this error,
even with the patch presented here. Like you had mentioned on
freebsd-scsi, the machine panic's roughly 50% of the time during boot.
Here is my `trap` with the patch applied. Due note that this is typed
by hand as the kvm I'm on doesn't allow for copy and paste:
Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address = 0x20
fault code = supervisor read data, page not present
instruction pointer = 0x8 :0xffffffff80187350
stack pointer = 0x10 :ffffffffac499810
frame pointer = 0x10 : ffffff0003782320
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, long 1, def32, 0, ran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 5 (thread taskq)
trap number = 12
panic: page fault
cpuid = 0
Uptime 5s
----------------------------------------------------------------
I wish I had further information to give. The information I provided
almost certainly pales in comparison to the submitters, but I believe it
relevant given the symptoms / deice are identical.
