From Bugzilla Helper: User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.2-2 i586) Description of problem: After booting my system looks fine (except that sometimes after the X login screen starts one or two ASCII characters are not displayed right on console screens being replaced by some unusual character). Then at some undetermined point, the system just locks up for no apparent reason. I've seen dumps from a kernel crash when I'm in run level 3. I can find no log messages that relate directly to the cause. I have found a message, "modprobe: Can't find module char-major-145" or "module char-major-81" but not sure if it's relevant to the problem. How reproducible: Couldn't Reproduce Additional info:
I have the same problem. System works fine for a while (around 30 hours or so) and then I get random OOPSes and eventually a kernel panic. But that's not all :). As I let the system run (even before getting OOPSes) certain things will stop working, for example xinetd (Yes, I tried re-starting it. Still no worky). Some system software stops working, too. For example, kill, ps, and top all lock up the terminal (no CTRL-C out of it). I'm also getting a modprobe: Can't locate module ppp0 . I don't know whether this is related or not. RedHat 7.1 Upgraded from 7.0. Stock kernel.
Ok; does this go away if you rm /etc/cron.d/kmod and then service crond restart ?
I think now part of the original problem stemmed from an edit I did to the /etc/cron.d/kmod file when I changed the 10 minute interval to 30 minutes. After I found the kernel crashing, I changed it back and it has crashed only once since. But I still have the funky character display problem and the modprobe errors/warnings.
We are experiencing similar problems here. However, they only seem apparant on computers using the 8139too network module. They have disappeared in one computer after changing the network card to a eepro100.
