Someone passed NULL to a netdevice notifier. That isnt allowed. Your call
trace indicates that it was passed by dev_open which would itself have oopsed
in that situation.

Beats me, and I also haven't managed to duplicate it

Hang on boot using latest -ac kernels with irda

2001-05-19 Thread Roel Teuwen 

Hello,

My HP Omnibook 5700CTX running redhat 7.0 and kernel 2.4.4-ac8 and up (I
haven't verified on older kernels) hangs on boot when bringing up
interface lo. Sometimes I experience an Oops at this point, one of which
I have copied by hand and decoded below.
When I boot a kernel without irda, the machine boots fine.

Attached is my .config and the decoded oops

If any more information is needed, do not hesitate to contact me.

kind regards,
Roel
