I start getting oops with both 2.2.16-3smp stock rh6.2 kernel as well as with custom compiled 2.2.17smp. The problem exist with both original nfs-utils-0.1.6 and with update nfs-util-0.1.9.1-1. The system is a pretty much stock rh6.2. 2 x P-III, ide harddrives and scsi (Adaptec 2940) for cd-rw. Oops piped through ksymoops follows. Any help would be appreciated.

I'd suggest upgrading both the kernel and nfs-utils to the latest versions (currently 2.2.19-6.2.1 and 0.3.1-0.6.x.1 respectively) to see if that helps.
