Comment 4 for bug 94944

Ok so this is caused by the combination of an SMP enabled kernel and the rt61 driver which seems to be both incompatible (see the link in the previous post).

The rt61 driver in feisty (20070322 beta) is :

the kernel on feisty amd64 (kubuntu and ubuntu) is :
2.6.20-12-generic #2 SMP

PS: The PREEMPT does not seems to be a problem as I use 2.6.15-23-386 PREEMPT on Dapper with the rt61-1.1.0-b1 and I do not experience the same problem.

Also I got the same output as the bug related to the rt2500 (this is not the same kernel module but it probably shares a part of the code) which is:
