Here is a panic on a 5-STABLE system.
I was testing out a system (Dell PII 400MHz) my father retired. I
thought heard some activity on the drive, so I ssh'd over to it then
exited right away (time to leave for a movie :)). It panicked shortly
afterward.
Although it is on a different bus and probably not the cause:
Dec 18 08:58:54 celt kernel: ata1-slave: FAILURE - SETFEATURES SET
TRANSFER MODE status=1<ERROR> error=4<ABORTED>
Just before panic:
Dec 18 08:56:03 celt kernel: ad0: TIMEOUT - WRITE_DMA retrying (2
retries left) LBA=5336671
Dec 18 08:56:10 celt kernel: ad0: FAILURE - WRITE_DMA timed out
Panic recovery:
Dec 18 08:58:54 celt savecore: reboot after panic:
initiate_write_inodeblock_ufs2: already started

Questions:
1. gdb -k is still in the man page. Is the feature pulled from gdb or
should the man page have it removed?
2. Why can I not get a full backtrace (bt full)? Only the first three
frames can be displayed that way. I can see all of the frames
without the "full" option.
Any ideas?
