Hi,
I am updated with the latest 4.5-stable release,
FreeBSD malgudi.procket.com 4.5-RELEASE-p2 FreeBSD 4.5-RELEASE-p2 #0: Thu Mar 14
14:50:11 PST 2002 kannan@malgudi.procket.com:/usr/src/sys/compile/MALGUDI i386
using cvsup. I am trying to get sound working (sony vaio pcg z505-LE, in case others
have tips). I do a kldload snd, things chug ok, no sound though, wierd error codes, so
I do a kldunload, and viola, a kernel core dump. I have a debugging kernel, as per
section 18.13 of the FAQ), and stashed away the coredump and have some prelim
analysis;
I have the dmesg out as attachment, as well as the backtrace from gdb. I had no
luck with nm -n...the particular address of the instruction pointer is not in the
base kernel image.
I don't know whether this has been reported earlier. I have the core dump, kernel
image
etc. saved away, if someone is interested.
Thanks,
Kannan
