Ok, Daniel, here are the results of the german jury :-) (EU insider joke)

And what may be of big interest for Justin: I am using the _old_ AIC7xxx driver.
The problem can quite easily be produced on my side. All you need is a (problem) host with NFS-server running and a client system. Then simply copy a lot of big files to the server. If you now go and read CD on the server you are in big trouble:
cpu load is shot through the ceiling and you cannot even type chars in a shell after about 3 minutes. Remember I am sitting in front of a dual P-III 1GHz with 1 GB of RAM and U160 SCSI, I simply cannot believe this. I have never seen such a thing under 2.2.
Regards,
Stephan
PS: I try to disable HighMem next.
