One more thing I noticed way up in the message log (hadn't noticed them at first): Feb 2 15:32:53 telethon ainit: Memory: Failed to release semaphore Feb 2 15:32:53 telethon ainit: Error: No such file or directory Feb 2 15:32:53 telethon ainit: Memory: Failed to release SHM segment Feb 2 15:32:53 telethon ainit: Error: No such file or directory Feb 2 15:32:53 telethon ainit: Memory: Failed to release SHM segment Feb 2 15:32:53 telethon ainit: Error: No such file or directory Feb 2 15:32:53 telethon ainit: No such file or directory Feb 2 15:32:53 telethon ainit: Memory: Failed to release semaphore Feb 2 15:32:53 telethon ainit: Error: No such file or directory Feb 2 15:32:53 telethon ainit: Memory: Failed to release SHM segment Feb 2 15:32:53 telethon ainit: Error: No such file or directory Feb 2 15:32:53 telethon ainit: Memory: Failed to release SHM segment Feb 2 15:32:53 telethon ainit: Error: No such file or directory Feb 2 15:32:53 telethon ainit: No such file or directory looked it up on google and it seems to be related to a bug that causes the kernel to lock under various circumstances, see http://lkml.org/lkml/2006/1/12/282 I wonder if it's related to the hardlock I'm having here. Thanks again for the kind feedback. fda Jesper Juhl wrote: > On 2/2/06, Fabio d'Alessi wrote: >> Dear sirs, >> I have a problem with a dual athlon xp running fedora/4 >> with the 2.6.14-1 kernel.
