Having had problems with SiI 3112A under the standard IDE drivers http://marc.theaimsgroup.com/?l=linux-kernel&m=107539618032329&w=2 I thought I would test my set of disks with some bad sectors that oops or hang the standard driver. I also tested them under high load (which also causes problems with the legacy drivers which can drop to PIO mode or just hang).
libata (2.4.25-libata3) is much more stable, managing 22 hours without problems, however has just hung with ata3: DMA timeout, stat 0x1 as the last log message (nothing before), box completely unresponsive. Will recompile with magic sysrq and with DPRINTK and VPRINTK defined. It wasnt actually accessing a part of the disk with bad sectors at the point, just under high load and accessing 3 disks. What is the best way of debugging this?
