Hi, I'm running 5.4 with a modified GENERIC kernel, and I recently
rebooted my system to find out that it hangs on probing ad1 with a
fatal trap 12.
Here's the entire error message
ad1 Timeout - Read_dma retrying (2 retries left) LBA 117231345

Fatal trap 12: page fault while in kernel mode

panic: page fault
cannot dump. no dump device
In my rc.conf I've got
dumpdev=/dev/ad0s1b
dumpdir=/usr/crash
For some reason it still says no dump device.
Right now I'm able to boot my system into safe mode, but not single
user or normal. I
think I might not be able to get core dumps b/c my system doesn't
get far enough in the boot process, so I'm trying to follow the
directions here
http://www.freebsd.org/doc/en_US.ISO8859-1/books/faq/advanced.html#
KERNEL-PANIC-TROUBLESHOOTING
but I'm not sure about this part of the instructions
% nm -n /kernel.that.caused.the.panic | grep f0xx
Do I need to replace /kernel.that.caused.the.panic with
/boot/kernel/kernel? If so, here' is the out put of
nm -n /boot/kernel/kernel | grep c063fb59
c063fb3c t init_turnstile0
c063fb4c t turnstile_setowner
c063fb78 T turnstile_alloc
c063fbb0 T turnstile_free
c063fbc4 T turnstile_lookup
Can someone help me out here? Am I going about it all wrong? Let me
know what other info might be needed. Thanks ~ Chris
Sounds a lot like you have a dead drive or controller to me. Have you
tried running the drive manufacturer's diagnostics on it?
