I'm most familiar with Suse and not familiar with kernel builds so last night I installed the pre-built Kernel:/HEAD/11.2 kernel from the opensuse build service. It's 2.6.37. It appeared to run without problem* so it seems that whatever fixed my issue was at least not specific to the Knoppix kernel. FWIW, I've put the dmesg at: http://pastebin.com/bWUNr8Ve It was late so all I did was copy a 1.7 GB file to and from the new disk on the VT6241A controller. No errors were logged. Incidentally, what's the best way of testing for this type of reliability? Tonight I plan to compile that kernel, which should confirm that I understand how to do it, and then I'll disable the VIA FIFO workaround as you suggest and see what happens. Cheers, Dave * PS There was one oddity, which was that Evolution crashed at around the same moment as I was mounting a logical volume from the new disk. I didn't investigate and it restarted OK.
