** Description changed:
Binary package hint: linux-image-2.6.15-27-386
+ The bug looks very similar to what I encountered on amd64 previously: #29020
Dear kernel folks/driver developers,
I have over the last few weeks encountered hangs at random occasions
(about every other day) on my server with two Atheros cards using the
madwifi driver. The hang seems to be in the driver when selecting
transfer speeds... The dist used is Dapper LTS 6.06. The hangs are
starting to worry me because of risk of facing corruption in the long
- run, I run ext3 so it should withstand some more hangs, but the
- situation is getting worse as time goes.
+ run, I run ext3 so it should withstand some more hangs at least.
+
+ The system runs perfectly for a day or two with both wireless interfaces
+ running perfectly, the interfaces are both up until the panics.
I'm running with two Atheros cards on the PCI bus:
0000:00:09.0 Ethernet controller: Atheros Communications, Inc. AR5212
802.11abg NIC (rev 01)
0000:00:0e.0 Ethernet controller: Atheros Communications, Inc. AR5212
802.11abg NIC (rev 01)
On the two networks I have WEP with 128bit encryption and the following
clients:
1st nw) A Dell laptop as client, with Intel Pro/Wireless
2nd nw) A D-link AP (2100AP)
The Kernel stack trace is attached and the hangs are consistent with the
same kernel bug location, I had similar problems with X86_64 which went
away after I migrated to x86_32 but to reappear now for some reason.
This seems to have started during november or december, I don't know
exactly since the server reboots automatically after 600sek when a
kernel panic has occured.
Is there more information you need to track it down?
Please help me.
Best regards
Philippe Höij
