I see definite changes; on heavy disk-access I got the following:
hdg: timeout waiting for dma
ide_dmaproc: chipset supported ide_dma_timeout func only:14
hdg: irq timeout: status = 0x58 { DriveReady SeekComplete DataRequest}
this was repeated several times, and ide3 was being reset, but the
kernel hung anyway after 5 minutes of waiting.
I must have an unlucky set of hardware (via chipset VP6 board, Live!,
ibm drives).
The following output is from 2.4.3-ac12:
