Dear Soren, Since my most recent kernel update, the intermittent TIMEOUT - READ_DMA warnings I get on my parallels install appear to have become somewhat less innocuous: ad0: TIMEOUT - READ_DMA retrying (1 retry left) LBA=38669679 ad0: FAILURE - already active DMA on this device ad0: setting up DMA failed g_vfs_done():ad0s1e[READ(offset=18188230656, length=2048)]error = 5 cvs update: in directory modules/tx: cvs [update aborted]: cannot read CVS/Repository: Input/output error In the past, this appeared to be a symptom of long and unexplained delays in Parallel's ATA -> image file operation, but were not harmful as the retried operation succeeded. However, it seems that this is no longer the case, with errors exposed to higher levels of the file system. Do you have any suggestions? Robert N M Watson Computer Laboratory University of Cambridge
