ALPHA UP2000 troubles

[Stefano <auro@nietzsche.mit.edu>]

Hi guys,

I installed Alpha-Debian 2.2_rev0 in a new UP2000 machine. 
UP2000 is a dual Alpha processor, tsunami architecture.
Kernel 2.2.17 that comes inside the installation does not support irq
handling on tsunami machines, so I moved to 2.4.0-test7 which is working
now in a Compaq ES40 machine (4 alpha processors !!). Well: while the ES40
works, the UP2000 hangs every time I access the network adapter. The
message is something like:  "kernel panic: skpur overflow" or "spinlock
whatever...." or a big page of trace numbers, with some assembler code and
tracing numbers...
Somebody has a running UP2000 with Alpha-potato-debian installed ???

Thanks

Stefano
