[BUG] zd1211rw on 2.6.23 oops ejecting the device

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello!

I've got one of the (in)famous usb wifi stick with the virtual cdrom...

The dmesg output (extract) is at the end of the message.
It seems that the oops is while ejecting. Please note that this is a perfectly
portable oops and oops on my x86 desktop pc with usb2.0 and on my arm920t based system with usb1.1.

Please let-me know if you want more informations!

Regards

Marc
