>Description:
Using the sym(bios) driver on both asus sc200 (810a) and tekram 390f (875).
Asus cuv4x-dls, dual pIII 1000mhz, 1gb, onboard scsi 160 and intel lan.
Trying to backup nfs mounted directory to tape using tar. System reboots.
custom kernel using -O2 -march=i686 -mcpu=i686, stripped down to mostly essentials.
Doing the same backup of nfs mounts, using the same hardware on a Solaris x6
works perfectly.

Also having problems with Solaris deletes on nfs mounts. A rm -rf fails to 
fully delete the tree and returns errors for existing files. I had this before
and when I switched a 3.1 rel system to nfs v2 it stopped being a problem.
Is the nfs v3 a known problem? I searched every where for info and did not
find anything specific.

thanks,
