When I got back tonight, I noticed that my machine had only been up
for about an hour. Turns out that it crashed:
================
IdlePTD 1ee000
current pcb at 1de928
panic: ahc%d: Timed-out command times out again
#0 0xf0196627 in boot ()
(kgdb) where
#0 0xf0196627 in boot ()
#1 0xf0112b03 in panic ()
#2 0xf01c41af in ahc_timeout ()
#3 0xf0107130 in softclock ()
================
I'm pretty sure I'm using most of the latest Adaptec code in
-stable. (at least it was the latest as of last week) Anyone have any
ideas on what could have caused a panic like that? There was, I think, one
user on the machine at the time. He may have been grepping through a large
number of files. (all the RFC's) I run xdm, so the X server was running
at the time.
Here's the dmesg output:

========================
This came along after the same user was logged on, presumably
grepping through all the rfc's again. There was also a ftp connection
open:
sd0(ahc0:0:0): timed out in dataout phase, SCSISIGI == 0x0
sd0(ahc0:0:0): BUS DEVICE RESET message queued.
sd0(ahc0:0:0): ABORTED COMMAND asc:4e,0 Overlapped commands attempted
, retries:4
The machine has been stable for weeks, so this is sort of a
surprise. Any ideas on the cause of this (and possible fixes :) ) would be
appreciated.
Thanks,
Ken
