(ie: the dmesg output) Finally, I got a little time to try other kernels than the official Fedora erratas. I compiled 2.6.10-rc3, applied the time-sliced-cfq-#2 io scheduler patch from Jens Axboe and updated the linuxconsole.sf.net multiconsole patch to work with 2.6.10-rc3, I depend on this functionality on my machine, my wife works on the machine or our children watch some cartoon or play games, etc, while I hack... :-) I attached the full boot log for both kernel-2.6.9-1.681 (also customized with the multiconsole patch) and 2.6.10-rc3. The uptime is now more than 2 hours with the new kernel, so far I haven't experienced similar problem with it. I played an AVI off the harddisk and recompiled the xorg-x11 src.rpm at the same time to create I/O stress. No problem with /dev/hda. What I miss are my removable devices. How to convince HAL daemon to keep /media/floppy and /media/cdrecorder? Or which patches should I apply from the Fedora kernel src.rpm? I created /mnt/cdrom and tried mounting /dev/hdc there (as root) but the mount hung... The kernel-2.6.9-1.681 Fedora kernel is basically 2.6.9-ac10, is there something in there what is not in 2.6.10-rc3 and a relevant fix to this? I am still on FC3/x86-64...
