Hello list,

I had a fileserver hang on me with the following call trace:

The machine has a RAID 10 configuration. Upon restart it came up with a degraded array.

3ware Storage Controller device driver for Linux v1.02.00.037. 3w-xxxx: AEN: ERROR: Unit degraded: Unit #1.
scsi0 : Found a 3ware Storage Controller at 0x3080, IRQ: 48, P-chip: 1.3 scsi0 : 3ware Storage Controller

This server is a fileserver running nfs-kernel-server 1.0.6.

Would a kernel upgrade help? Please let me know if I can provide any further information.

TIA
