This is my first post to this list, so I hope I get this email formated correctly. If not I will endeavor to correct my mistakes in future postings. I tried sending this previously but did not see it show up in the mail, so I'm trying again. If they both show up, my apologies. I've seen several other postings on hangs and slow system time updates during hangs, but no indication if anything has been found to resolve the issues. Here is my system info: Soyo Dragon Plus (Via KT266A chipset) AthlonXP 1700+ 512MB DDR2100 using on-board lan and sound Geforce3 ti200 WD 120GB primary master Maxtor 120GB master on Promise Ultra I have the hangs both with and without the livna drivers. The hang occurs at varying times. Anywhere from a few minutes to many hours of running. I do not leave this machine up 24/7, so it always happens after a cold boot for the day. Some days I may be on for 4-5 hours and not have a hang. It appears that if I wait long enough during a hang, I can usually get a virtual terminal and do a shutdown. 2111 kernel appears to be OK, although I have had it hang after a reboot from a lockup in another kernel. Never had a hang with cold boot into 2111. One thing I have noticed is that sometimes after a hang, the system time is off by a significant amount (10s of seconds to minutes). I have two other computers running FC5 and they do not exhibit this problem. Both of those systems are different mixes of hardware vs the problem system. All three systems are upgrades from FC3, and one has been upgraded from FC1 => FC3> FC5. That one runs fine. I hope someone can point me at the solution to the problem. B.T.W., I'm using the problem system right now, and it has been fine for the past week on 2111 kernel. I've run smartctl and checked my drives and they are OK. No errors other than a few reallocated sectors. The sectors are not new and have been slowly growing for a couple years. I find that all my WD boot drives have the tendancy to do this, while my Maxtor and IBM do not. Thank you in Advance, Lloyd Here are some of the relevant sections of the error messages from the message log: kernel 2122 Jun 7 10:28:52 HAL5000 kernel: Unable to handle kernel NULL pointer
