Subjecteth0: Bus master arbitration failure
I was wondering if anyone knew if this had been resolved
or see this problem too. I am having the same problem.
However, I am using 2.5.64 kernel and I have tried
both an eepro100 and a 3com-tornado ethernet card.

I use netperf to create a load of packets, and within minutes
I receive a few "eth0: Bus master arbitration failure, status ffff"
and then the machine locks up. (This seems to only happen
with a heavy load.)

I have no problems when I use 2.4.18-3 smp kernel (Redhat 8.0)
and I have also used a 2.4.19 kernel a while back with no problems.

I am using a 2-way IBM Netfinity 4500 and a 4-way xSeries 350.
No problems on a uniprocessor.

Thanks, for any info.

Regards,
Joy
