Re: ide problem - is this a known problem, or is the disk dead?

I'm running 2.4.21-rc3 on the host where i got this today:

hdc: dma_timer_expiry: dma status == 0x20
hdc: timeout waiting for DMA
hdc: timeout waiting for DMA
hdc: (__ide_dma_test_irq) called while not waiting
hdc: status timeout: status=0xd0 { Busy }

hdc: drive not ready for command
ide1: reset timed-out, status=0xd0
hdc: status timeout: status=0xd0 { Busy }

hdc: drive not ready for command
ide1: reset timed-out, status=0xd0

Now I'm trying heavy reads/writes on the drive which failed,
but I'm unable to generate any error (yet). I had more than
2 weeks of uptime with this kernel.
