Hi, I am running FC2 and FC3 on a no-name laptop (2.8 Ghz 512Mb). FC3 is a very up-to-date kernel - about 2.6.11 I think. Now when the machine runs FC3 in a command-line mode it seems very stable and services Samba clients well. When I start X, the machine hangs within minutes. It is no longer possible to ping the machine, no longer possible to telnet to it - it just "locks up". The only way to recover the machine is a power off and power on - I get lots of horrible inode and directory error messages when fsck is run. I do not have the technical knowledge to know where to find the relevant log files that might show what happened just before the failure. If you can tell me where to look, I can post more diagnostic info. When the machine runs an FC2 kernel (2.6.7 ?) the machine seems stable for days, running either command line or with X active. I am going to run some more tests on FC2. Can someone tell me what extra diagnostics I need to collect to help in tracking down this problem? Thanks Clive
