[2.6.17.7 BUG] bonding + wifi -> BUG: scheduling while atomic

[Mark Hindley <mark@hindley.org.uk>]

Hi,

I get the following BUG: scheduling while atomic when I remove my wifi
pccard (madwifi) which is bonded to the wired interface in active-backup
mode.

I think this is bonding related, as there is no BUG logged when the wifi
interface is standalone.

This is 2.6.17.7, but has certainly existed with all 2.6.17. 
System: Acer Aspire 1350, preempt kernel, both bonding and madwifi
drivers are modular.

Let me know if you need more info, or if I should take this somewhere else.

Thanks

Mark
