Howdy,
I am testing and fixing the new IPsec code we have and just came
across this:
Unread portion of the kernel message buffer:
panic: clist reservation botch
cpuid = 0
KDB: enter: panic
#0 kdb_enter (msg=0xc074a2fe "panic") at ../../../kern/subr_kdb.c:310
310 }
(kgdb) where
#0 kdb_enter (msg=0xc074a2fe "panic") at ../../../kern/subr_kdb.c:310
#1 0xc0524874 in panic (fmt=0xc075155d "clist reservation botch")
at ../../../kern/kern_shutdown.c:547
#2 0xc05721fe in putc (chr=102, clistp=0xc1dd4038)
at ../../../kern/tty_subr.c:104
#3 0xc0569333 in ttyoutput (c=102, tp=0xc1dd4000) at ../../../kern/tty.c:769
#4 0xc0569437 in ttyecho (c=Variable "c" is not available.
) at ../../../kern/tty.c:2406

#11 0xc0506b58 in fork_exit (callout=0xc0509500 <ithread_loop>,

I don't think I'm doing anything "funky" but who knows. Anyone have
their hands in the tty code at the moment?
This is on CURRENT of a week ago, kernel config is attached to the
email, and this system is running on VMware.
Let me know what other information I can provide.
Best,
George
