Hi,
I am making freebsd run on xen as domU. I am having the following issue:
1) I see a fatal double fault happening.
2) I have set up all the dumpdev configuration correctly, yet the system does not dump on panic.
3) I built a debug kernel to get a traceback. However since its a kernel page fault, the trace backs are not relevant.
I guess to proceed further I would have to have the dump file. Here is the relevant configuration information
sysctl -a | grep core
kern.corefile: /var/crash/%N.%P.core
kern.nodump_coredump: 0
kern.coredump: 1
kern.sugid_coredump: 0
kern.cpu_cores: 0
o/p from /etc/rc.conf:
dumpdev="/dev/ad0s1b"
AN# cat /etc/fstab
# Device Mountpoint FStype Options Dump Pass#
/dev/ad0s1b none swap sw 0 0
/dev/ad0s1a /boot ufs rw 2 2
/dev/ad0s1e / ufs rw 1 1
Can some one help me get the dump core part work correctly.
Thanks
