Hello My T40 IBM Thinkpad laptop is running FC3 on XFS filesystem. It used to be rock-solid, but recently, then and now it 'freezes' (maybe once a week). There is absolutely no sign in var/log/messages after boot-in on the cause of the freeze, which is sudden. There is also no correlation between what I do, how heavy the use, etc. AND the freeze. The only way back is hard-reset. I am trying to figure our what is causing it: hardware error? If yes, harddrive or memory? One clue; some of the last files that were open before the freeze will contain only \0 characters. E.g. bash$ od -c .lastfile 0000000 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 * 0010740 \0 \0 \0 \0 \0 \0 \0 \0 \0 0010751 This is quite annoying as you may imagine. Cheers Gaspar
