hi all,
i got this the other day and don't know what it means other than it refers to the drives. this is a older 200 mhz machine with a fresh RH9 install.

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: status timeout: error=0xd0LastFailedSense 0x0d
hdc: drive not ready for command
hdc: ATAPI reset complete
[root@localhost cdrom]# hda: dma_timer_expiry: dma status == 0x21
hda: timeout waiting for DMA
hda: timeout waiting for DMA
hda: (__ide_dma_test_irq) called while not waiting
hda: status error: status=0x58 { DriveReady SeekComplete DataRequest }

hda: drive not ready for command


this has happend a few times before sometimes with longer messages. this occured while copying a file from a cd to the hard drive. any help is appreciated.

probably your cdrom doens't like UDMA mode. try to switch it to PIO mode (1-4)
