DOH! ata_alloc_request failed!

[Mike Jakubik]

Hello,

I keep seeing the following in my logs, should i be worried?:

Sep  4 03:01:29 ns2 kernel: DOH! ata_alloc_request failed!
Sep  4 03:01:29 ns2 kernel: FAILURE - out of memory in ata_raid_init_request
Sep  4 03:01:29 ns2 kernel:
g_vfs_done():ar0s1f[WRITE(offset=107303043072, length=16384)]error = 5

The disks seems fine as far as smartmontools can tell and there is no
visible data loss or corruption. This an an Opteron system running in
AMD64 mode on a Nvidia motherboard using the on-board ata raid. I've
seen some posts from other people complaining about this, but no real
answer as to the cause of the problem.

Thanks.
