Inspired by what you say about timeouts, I thought perhaps increasing the timeout from 10ms to 1s might make a difference -- that worked! ... except that now, it's working regardless :-( So, I've no idea if that's really related to what's going on, because I've now gone as far as reducing the timeout to 5ms and it's _still_ working fine, so perhaps some part of the SATA subsystem was in a state that was somehow reset by waiting a bit longer for the startup once, and that's somehow "fixed" it. It is still working despite powering down the machine for a while, so I'm guessing whatever changed is something to do with the state of the hard drive. Sadly that means that I've now lost the ability to test this, since trying any of the versions that were previously failing now work. Anyway, Alexei, try increasing the timeout (i.e. the value being assigned to timeleft) --- if that works for you too, it seems pretty harmless, so might be appropriate for wider adoption. =-=-=-=- Meanwhile, the SD has reverted to being broken, so that ext2ls just hangs in the read, by the looks of it :-/ Cheers, Phil. -- |)| Philip Hands [+44 (0)20 8530 9560] http://www.hands.com/ |-| HANDS.COM Ltd. http://www.uk.debian.org/ |(| 10 Onslow Gardens, South Woodford, London E18 1NE ENGLAND
