[SeaBIOS] SeaBIOS - Network Problem - LSI53C895A Interrupt problem

[Gerhard Wiesinger]

Hello,

I'm having the following problem with Knoppix 6.2 since commit 
a65f417c8430ce6781cbbfe84381a97d60628d81 of seabios:

Linux Call trace and AMD pcnet network interface doesn't work. Looks like 
that interrupt is disabled.

I bisect it down to the following commit:
a65f417c8430ce6781cbbfe84381a97d60628d81 is the first bad commit
commit a65f417c8430ce6781cbbfe84381a97d60628d81

     Consolidate DSDT copy-and-paste PCI IRQ code into method calls.

     Use method calls in LNK[ABCDS] object methods - this reduces the
     cut-and-paste code.  It also makes it simpler and the object size
     smaller.

Any ideas what the problem might be and how to fix it?

Thnx.

Ciao,
Gerhard
