[parisc-linux] HP B132L hangs

[Sebastian Brueckner]

Hi!

In the last few days the B132l I use as DSL router completely hung 3 
times. Every time requiring a power cycle to revive it. It is running 
Debian testing with kernel 2.4.18-hppa.

To test the machine I tried to compile a new kernel. After compiling a 
few files everything hung and spit out the following messages:

scsi0: (2:0) Synchronous at offset 8, period 100ns

... and so on and so forth ...

The power seitch does nothing, only power cycling helps. I tried 
compiling the kernel again with the same results...

What do these messages mean? Is the hd defective or is it some problem 
with the scsi bus?

The machine worked flawlessly for half a year... I have no idea what 
went wrong!

Thanks in advance,
