hmmm... my athlon64 hung last night. hard lockup, had to powerfail it.
of course the screensaver was in powersave mode (kde) so I dunno what
the desktop looked like.

syslog has nothing, and messages has:

Oct 25 07:37:01 athlin1 kernel: klogd 1.4.1, log source = /proc/kmsg
started.

all that was running was a kde desktop with a console session doing a
copy to a usb hard drive (IDE drive in removable case) via a smb mount...

the box is about 6 months old and this is probably the first time it's
ever done that.

I'm more annoyed than anything.. is there anything else I can check (dumps?)

I'm not used to troubleshooting failures on Linux boxes... it could be
hardware, but I dunno, and this box hasn't had a history of that and
other than the USB drive it's unchanged in months.

Because of the infrequency of the event, it once only, I would suspect some
sort of power spike throwing the PSU off stride for a millisecond.

Might be worth updating to KDE 3.4.3 from kde.org if it happens again (been
running the non-official Slack packages since it was released, not had a
problem.)

Which kernel? recent 2.6 series have usbmon, USB debug stuff you
may turn on to get an idea what's happening.

Running USB IDE drives is iffy with some USB<=>IDE bridges (chip in
the USB enclosure).

More info?

2.4.31.
Stock kernel with ACPI enabled.
Athlon 64 3000+ (socket 754), MSI Neo something MB (KT800 chipset.)
512MB DDR400
Nothing overclocked.
external USB 2.0 Case with Maxtor 250GB IDE drive (8MB/7200RPM) inside.
unable to replicate -> I filled it right up today and nothing...
so I dunno what else to say... just wondering what other hints may be
left behind.

eventually... I just rebuilt this dang box like a month ago.

Stuff happens ) Maybe you bumped the cable?

See http://linux.exosec.net/kernel/2.4-h...-hf6/CHANGELOG
try 2.4.31-hf6? There are some x86-64 fixes mentioned in there might
ring a bell.

Turn on SCSI verbose errors and USB debug might shed some light, but
the odd lockup is difficult. One lockup more so I've had trouble
with (no-name) DDR-400 memory, maybe a compile test loop, perhaps:

cd linux-2.4.31; cp vmlinux ..
while true; do make clean; make bzImage -j4; cmp vmlinux ../vmlinux >> ../result; done

Checked for BIOS update?

latest BIOS and stuff... and that's the only hiccup since I built that
box in January, so I'm not bothering for now... but I like the idea of
USB debug stuff if it happens again.

Like I said, unable to replicate, so I'm putting down as phase of the
moon for now...
