Hi !
I have box running 4.2-STABLE (last cvsuped 15 February 2001).
It has four Realtek 8139 PCI cards. Before last night system runs ok.
But now it random panics. Nothing was chaged within last two weeks.
Kernel config and kernel debug whith gdb attached to this letter.
If you have any ideas how to fix the problem - tell me.
I suppose that one of cards became broken. But which of them ?
