Subject: [Bugme-new] [Bug 2851] New: System takes 100% CPU and kernel log has
*loads* of assertions
http://bugme.osdl.org/show_bug.cgi?id=2851
Summary: System takes 100% CPU and kernel log has *loads* of
assertions
Kernel Version: 2.6.6
Status: NEW
Severity: high
Owner: niv@xxxxxxxxxx
Submitter: atlaste@xxxxxxxxx
Distribution:Debian
Hardware Environment:
Small piece of lspci:
0000:02:05.0 Ethernet controller: Marvell Yukon Gigabit Ethernet
10/100/1000Base-T Adapter (rev 13)
0000:02:0a.0 Ethernet controller: Intel Corp. 82557/8/9 [Ethernet Pro 100] (rev
05)
Furthermore, it's an intel ich-5r motherboard from ASUS: P4P800E-deluxe
(http://www.asus.com/prog/spec.asp?m=P4P800-E%20Deluxe&langs=01)
The first ethernet controller appears to be causing the problem. However, it
should be noted that the first ethernet controller is used way more often,
while the latter is merely used for internal traffic.
The first ethernet controller is on a LAN with 1500+ computers. This also means
weird stuff could be happening here, although I think that's unlikely in this
case, when looking at when the problems are occurring.
Software Environment:
Nothing special, running a number of services.
Problem Description:
The log should provide enough information. Somehow it appears SSHD causes the
problem, perhaps in combination with a screen, and it is caused at arbitrary
times. (about 2 times a day sometimes). This is just a small snippet; my entire
HD ran full with 50GB of logs because of this bug, in merely two hours.

Steps to reproduce:
Not entirely sure. Usually I login with SSH and the bug arbitrarily emerges.
As a last note: 2.6.4 appeared to have this problem too.
