Verbose dmesg is attached. >Description: 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. >How-To-Repeat: /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. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
