S=F8ren, It looks like I spoke to soon when I said the world was safe for Promise Ultra users: ad3: ad_timeout: lost disk contact - resetting ata4: resetting devices .. ad3: HARD WRITE ERROR blk# 6594768ad3: DMA p= roblem en countered, fallback to PIO mode ad3: DMA problem encountered, fallback to PIO mode done ad1: UDMA CRC READ ERROR blk# 10522095 retrying ad3: ad_timeout: lost disk contact - resetting ata4: resetting devices .. done At this point the machine is unpingable & will not respond to a break on the console. This is with a ccd stripe set, striped across 4 Maxtor "Diamondmax" drives attached one per channel to 2 Promise Ultra cards. `The kernel sources are dated slightly before the build time in= the below boot messages. (I'd have given you verbose messages, but this is a transcript from the serial console logs & the machine is wedged solid right now). I'm running with a timeout of 30 seconds as I was hoping to avoid a 'lost contact - resetting' situation as all hell breaks loose when those appear. BTW, I'd really like a tunable or some way to prevent a permanent fallback to PIO. I'm more than willing to tolerate one hard error per week or so on a disk which sees 10s of gigabytes of data read & written between errors. =20 The driver was much more stable back in July when (I guess) you just ignored errors. Using a July kernel, this machine will stay up for months with nothing but the occasional: ad3: status=3D51 error=3D84 ad_interrupt: hard error It never looses contact, never wedges. Oh for the good old days..
