Might be a mandrake source thing, not liking nforce2 perhaps?

If you don't mind a bit of work, you could download current standard 2.4.23
kern source, add my patches, compile with acpi and uniprocessor ioapic,
Athlon etc. use the onboard nic, and try it with apic_tack=1 kernel arg.

Ross.

Transfered 1,8 GB without any crash. As the nvnet module seems to be part of 
the NVIDIA released drivers I use my Realtek 8139 (like before when I had the 
crashes). I just compiled the NVIDIA drivers and will give it a run. I am 
wondering where the actual bug might be located as you remember that I did 
not use APIC in the first place.

Thanx for help
