frame pointer = 0x10:0xff80fdb4
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = idel
interrupt mask = net tty <- SMP: XXX
kernel: type 12 trap, code=0
stopped at m_freem+0x1c: cmpl $0,0(%ebx)
>How-To-Repeat:
I haven't been able to narrow the event to a specific event other than I cvsup'd this morring after this issue (http://www.freebsd.org/cgi/query-pr.cgi?pr=41459) was resolved.
My mylex raid controller doesn't seem to be a valid dump device so I am unsure what else to do. I've loaded DDB into the kernel and get to a db> prompt. Any guidance would be appreciated.
