Hi

When using 2.5.69-mm9 which includes Manfred's unmap-after-free patch I
ran into a use-after-free bug in e100 that just might be real.

I ran the two oopses through ksymoops to get some more detail but since
ksyms doesn't exist in 2.5 anymore it failed to resolve the EIP (e100 as
module). But fear not, the EIP is in the original report by kksymoops
and I've included it below.

(identical in both oopses)
EIP is at e100_rx_srv+0x4ac/0x514 [e100]

The two ksymoopsed oopses are attached.


Driver output at init:
(no module options)
