nfs version 2 access and kernel 2.6.x freeze

nfs version 2 access and kernel 2.6.x freeze

[Axel Beier]

Hi,
after upgrading to kernel 2.6.0 on client-side i cannot copy data from 
my (old) nfs server. The server is old (running SuSE 7.1 with a 2.4.19 
kernel) and supports only nfs version 2.
But with kernels 2.6.0 upto 2.6.1-mm2 after few seconds of copying a 
remote-file to the client the client hangs completely.
Kernel was compiled with gcc 3.3.1 and has preemptive enable.
No entry in the syslog....

Any idea except upgrading the server?
No problems with kernel 2.4.x....

Regards,
Axel

Hi John,
no success. Tested with 2.6.1-mm3 and pre-emption off. System freezes 
after 10-20 seconds during reading data from the nfs-server.
