Hi Jean,

I hope you are the right person for this problem. I've found your E-Mail address in the code..

I use the kernel pcmcia driver for the aironet-card. Every time when I copy some larger files over the net with samba, scp or nfs, I get a kernel-oops. After that my keyboard hangs and I have to reboot. Alt-SysRq-XY still works. Today I saw (In xosview) that the keyboard still generates Interrupts.
With Kernel 2.4.19 there are no such problems..

Thank you.

Kind regards

Marc
