Possible problem documented in irc conversation below, too lazy to rewrite all that :-)
Have there been some behavioural changes in this area recently? Linux happily overwriting the HPA seems to have happened between fc3 and fc4. Could be some userspace partitioning related/bios brokedness thing too I suppose?
02:04 * pp tries to figure out host protected area stuff 02:04 < pp> _apparently_ these stinkpads have a hidden partition containing windows xp etc. 02:04 < pp> which the bios protects 02:04 < pp> linux happily ignores that setting and tries to use that area as well 02:05 < pp> which works until you eg. resume from suspend and the area is locked again 02:05 < pp> which makes your box pretty unhappy 02:05 < pp> at some point the behaviour was to just ignore the extra space 02:06 < freitag> pp: i think i have machines that print at boot they ignore the host protected area 02:06 < pp> so whatever is there got nuked :-) 02:07 < pp> apparently could even be bios setup etc. on some models 02:07 < rdd> they can reinstall XP from there too (if it's not nuked) 02:07 < pp> yea 02:08 < pp> basically my laptop went into a state where in "normal" setting it worked until resuming from suspend, after which it got io errors 02:08 < pp> in "secure" mode (no OS access to hpa) the box refused to boot at all 02:08 < pp> and in "disabled" it's totally happy 02:08 < pp> but the fancy ibm stuff disappeared 02:09 < pp> oh well 02:09 < freitag> tell linux-ide
