Description Dmitri A. Sergatskov 2000-09-16 05:12:30 UTC
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.
Sincerely,
Dmitri.

Comment 1 Rex Dieter 2001-04-30 18:23:30 UTC
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.

Unable to reproduce in latest release.
