Subject[NFS] Oops in 2.4.2 - please give advice
Date

Hi,
I have this Oops with the following config:
- Stock 2.4.2 (no patch)
- I have LVM volumes (0.9.1b5)
- I have Raid0 + Raid5 volumes (v0.90)
- Filesystems are ext2
- The machine is a PII 733 with SCSI and IDE disks.
- The chipset is a VIA but DMA is disabled (for IDE disks).
Thanks for any help
