Subject2 * Oops on 2.4.17
Hi,

While loading aic7xxx (a new one, with old everything is ok) my machine
crashed completly (no magic SysRq). I'm not sure is it 8139too bug or
aic7xxx (probably both). After restart with zero ethernet traffic aic7xxx
loaded successfully, but oopsed (not crashed) while rmmmod. My machine
is SMP (2*PIII):
Linux gruby 2.4.17 #1 SMP czw gru 27 14:26:28 CET 2001 i686 pld

lspci -vvv shows this about my 8139:
