Earlier today (after 4+ days of uptime) the machine disconnected one of the SATA discs despite the fact = that I'm running with Ville-Pertti's serialization patch. I have two 250GB SATA discs, one Western Digital and one Maxtor. After looking at the logs from today, and grep'ing some old logs, I noticed = that it seems more common for the channel with the WD disc to lock up. My = logs don't go back far enough that I can say it has always been like that, = but it looks that way from the logs right now (but I only switched channels for = the discs once, so the sampling is very limited and the result could be = entirely coincidental). I have updated my system to sources from 2004.08.09.13.00.00 without any patches (because I saw some commits to the ATA code in the last couple = of days). The base code now allows me to at least start the SMART monitor = and run some stress tests. I'll report back when/if it fails. By next week = I'll probably have a Promise SATA150 TX4 that I will use instead. It will be = very interesting to see if that one also will give me problems with the WD = disc. /Daniel Eriksson
