My /etc/fstab contains:
# Device Mountpoint FStype Options Dump Pass#

Swap is 8 Gbytes and we are running with 4 Gbytes of memory.
My issue is we are trying to track down an intermitten crash in the kernel,
but cannot obtain a crash dumpfile. When a crash occurs I am seeing the
following on the console:
Fatal trap 12: page fault while in kernel mode
cpuid = 5; apic id = 05

uptime:2d3h44m24s
Dumping 2020MB:Aborting dump due to I/O Error
Status==0xb, SCSI status=bx0
Dump Failed (ERROR 5)
This seems to be a failure in cam/scsi/scsi_da.c in dadump(). This was
working for us under FreeBSD 6.2 (we just recently switched to using 8.0).
Googling only turned up some issues way back in 4.x with different SCSI
controllers, nothing for 8.0.
Any pointers are appreciated. I get the same behavior when I force a
panic using 'debug.kdb.panic=1' as well.
Thanks,
Patrick
