hdb status error, dma disabled by itself on hda and hdb

["H.S." <hs.samix@gmail.com>]

Earlier today I noticed these messages in /var/log/syslog:

Feb 21 11:38:17 localhost kernel: hdb: dma_intr: status=0x00 { }
Feb 21 11:38:17 localhost kernel: ide: failed opcode was: unknown

Feb 21 11:38:18 localhost kernel: hdb: DMA disabled
Feb 21 11:38:18 localhost kernel: hdb: drive not ready for command



I think I was doing "updatedb" at that time. I have just now re-enabled 
dma on the two disks. I am using Debian Testing with 2.6.18-3-486 kernel.

I am also using noflushd to switch off hdb for most of the time. The OS 
is on hda.

Anybody has any idea what is going wrong? Some problem with my disks?
