Disk error?

[Andrej T.]

Pozdrav,

Imam dva nova enaka diska v RAID 1 (hda,hdc) polju in na zadnje sem 
dobil tole sporocilo v "dmesg" :

hda: dma_timer_expiry: dma status == 0x20
hda: timeout waiting for DMA
hda: timeout waiting for DMA
hda: (__ide_dma_test_irq) called while not waiting
blk: queue c02e7640, I/O limit 4095Mb (mask 0xffffffff)

Na googlu sem prebral, da je to povezano z DMA, sedaj pa ne vem ali je 
problem v kernelu ali v disku. Kaj pravite vi?
