Hi,
I'm seeing a kernel panic on -current (9/26) when booting with a SanDisk
ImageMate II USB comact flash reader plugged in. The panic occurs after
the kernel has loaded when the first rc.d scripts execute (dumpon,
vinum, etc).
If I boot with the device disconnected, I can plug it in and unplug it
without problems later.
Attached is a boot trace and a gdb backtrace. (gdb crashed on me, so I
couldn't get more information.) Here's the relevant info from the trace:
SMP: AP CPU #1 Launched!
