Randoms hang of onboard i8255x controler ( SMP server )

[Brancaleoni Raffaele]

Hi,

Some more informations about this problem : 

I tried to disable IRQ sharing in the adaptec driver ( an AIC7xxx is
included
on the motherboard), this had no effect, I still get the same behaviour
from
the i82558 adapter.

I also tried to increase debug level in the module : no relevant
informations
about the lock-up.

I tried compiling the eepro100 module with suggested optimisations for
SMP : no effect.

Disabling SMP in the kernel did not solve the problem.
I even tried different optimisation levels for the kernel without
success.

I noticed the card stops issueing interrupts when it hangs.
Even removing the other NIC doesn't solve the problem ( There are no
interrupts
conflicts anyway ).

Tried linux-2.2.5ac7 & linux-2.2.6 kernels btw. Still no success.

I'm really disappointed. Could anyone help ? I ran out of ideas.

Thanks,

Raffaele


P.S. : 

Mii-diag gives for eth0 ( I removed the supplementary EEPro100+ so eth0
is now 
i82558): 

MII PHY in use is 1.
