I got a series of oopses on an IBM T20 laptop when it was moderately loaded (running dpkg):

This machine has previously been quite stable running this kernel, but I just got a Netgear MA401 wireless card and started using it with the 2.4.19 orinoco_cs driver. The card and module weren't installed at the time of the crash, but they had been earlier in the day. Could it be a bug in that driver?
