SubjectSimultaneous network/IDE traffic = reboot
Hi,

I have stumbled upon a _big_ problem with my machine. It makes a silent
and instantaneous soft reboot when performing (pretty tough) disk and
network access at the same time. I noticed this when trying to transfer
some 10+ Mb files from this machine as the screen just turned black and
the BIOS "welcome" screen appeared. No kernel oops or other message,
just a plain reboot. I can't find anything in the logs either. *sigh*

If I am using the machine "normally" everything works just fine. That is
no fiddling with large files or performing any extreme network activity.

I have found a very simple way of reproducing the crash. Just do a 'ping
-f' to the machine for a second or so and run 'hdparm -t /dev/hda' at
the same time. It reboots almost immediately. One more thing, if I do
'ping -f' locally no matter to what address/if, I can't make it crash.
But from another machine - reboot.

I have checked everything I can think of, i.e. conflicting IRQ:s, DMA
etc. I have tried to reassign almost everything in the BIOS but to no
avail. Also tested the 2.2.9 kernel but same thing there. I do not know
what to do next, does anyone of you have an idea?

Some facts about the machine:
Intel Celeron 333
128Mb DIMM
Motherboard Abit BH6 (Award BIOS rev 4.51PG)
2pcs NIC 3Com 3C905B-TX
Seagate Medalist ST38420A IDE 8,6Gb
Redhat 6.0 (kernel build 2.2.5-15)

Attached are some files from /proc that may or may not help you to help
me.

Regards,
