Bug#574555: BUG: scheduling while atomic: irq/11-b43/2018/0x00000101
I find a similar oops very reliably whenever there is moderate network
traffic, like updating squeeze. This happens on 2.6.32-3-686,
2.6.32-5-686, and 2.6.33-2-686 from experimental, but not at all on the
earlier squeeze kernel 2.6.30-2-686. Soon after this the system locks up
completely.
This makes the b43 driver in the current kernels more or less unusable
for me.
