This is a standard i386 system with an external SCSI array attached.
Verbose dmesg is attached.
This system performs fine on an April 22 2007 kernel. I updated to
-current on July 4, 2007, and immediately started seeing these panics.
Upon further testing I found that I could read data just fine from the
SCSI drives, but that attempting to write to the drives resulted in
this panic. The panic message and backtrace are attached.
/dev/da7 is my test drive. I can run:
# fdisk /dev/da7
and read the slice table as often as I wish without trouble. A simple
write operation such as
# fdisk -BI /dev/da7
panics the system. This does not happen every time, but if I run this
command a few times in a row it regularly and reliably panics. My
record is five successful "fdisk -BI /dev/da7" runs one after the
other in quick succession before the sixth panics the system.
