After upgrading to kernel version 2.6.6-1.435, I'm having an issue where after the machine is up for several hours, all of a sudden all of my filesystems (ext3) change to read-only. I tried a stock 2.6.7 kernel built with the config file for fedora-2 2.6.6-1.435 and have the same results. The problem does not seem to occur using kernel 2.6.6-1.427, at least I haven't had it happen yet. Unfortunately, since all the filesystems are read-only, I have no debug info or any idea what exactly is happening, because the system logger can't write to the system logs once the root fs becomes read-only. Screensaver had kicked in too, so no useful info on the monitor either, other than lots of failed journal updates related to the fs being read-only. Upon reboot, the fsck of the / filesystem always fails with messages about inodes being members of orphan nodes. Single user fsck fixes that and the subsequent reboot works fine. Any ideas, or suggestions as to what I can do to get more info on what is going on? Maybe logging to the console as well as to /var/log/messages and turn off the screen saver, to get more info about what happens? I'm running on a single processor AMD athlon at 1.4 Ghz, 1 Gb RAM.
