| |
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.
