RH 7.2 + nVidia drivers. Since it's a server I don't run or even have a graphical surface installed. Hang means: Console (Textmode) doesn't respond anymore, can ping to machine okay, can connect to services but don't get a respond. Some people said it might be a problem with the harrdisk- layer. Assuming this would for sure make clear why the running kernel can work properly but neither can a service spawn new children (ssh, ftp, ...) nor could syslog write to disk (and maybe cause everything to stop) nor could the swap-space be accessed. I don't know what to believe ... I just know I have to do something to find out the cause. Waking up at night because of a bad dream that the server might be locked up again can't be okay :-( I'm running latest stable RedHat-kernel as well - so I assume there are no problems with the ide-drivers from RedHat ... otherwise I guess they would have released a fix-pack. Does anybody know about problems with harddisks? But remember: It's not said that it ARE the harddisks / the ide- layer. Might be something else. So I guess we need to keep open- minded.
