Hello!

I'm having two new Maxtor 160GB disks in RAID 1 setup and lately I saw
the following error in "dmesg" :

Feb 23 04:03:42 www kernel: hda: dma_timer_expiry: dma status == 0x20
Feb 23 04:03:42 www kernel: hda: timeout waiting for DMA
Feb 23 04:03:42 www kernel: hda: timeout waiting for DMA
Feb 23 04:03:42 www kernel: hda: (__ide_dma_test_irq) called while not
waiting
Feb 23 04:03:42 www kernel: hda: status timeout: status=0xd0 { Busy }
Feb 23 04:03:42 www kernel:
Feb 23 04:03:42 www kernel: hda: drive not ready for command
Feb 23 04:03:58 www kernel: ide0: reset: success

What could cause the problem? I checked the IDE cables (80 pins) and
they are OK. The whole machine is new. This happens on both disks.

My configuration :

Motherboard : GigaByte GA-8IPE1000 series
Processor : P IV 6 Ghz
RAM : 1 GB
Disks : 2 x Maxtor 160GB
System : RH 7.3, kernel 2.4.24
