decoded oops follows, 100% reproducable.
Dell Latitude CPxJ750GT, PIII-750, Xircom RBEM56G100-TX,
kernel compiled with GCC 3.1. NB, 2.5.18 compiled with
GCC 3.1 works fine.
I tried recompiling with RH7.3 GCC but I still get an oops
on boot - I can't decode it since it scrolls maybe a dozen
screenfuls before stopping, so here's the GCC 3.1 one:
ksymoops 2.4.4 on i686 2.5.18. Options used

My laptop also oopses on boot, but this patch makes things work again:

I get an oops also in pci_unregister_driver, which happens because
driver_list in the device structure is never initialized. I'm now
running with this patch which seems to work:
