View Full Version : Update to kernel 2849 causes mount problems

18th November 2006, 11:31 PM
I finished an install of FC6 and today went ahead and updated all the packages.

Kernel 2849 fails to boot. Kernel 2798 still works.
I have 5 drives in this server. All IDE. I have 1 raid 1 partition.

Shortly after loading the kernel and initrd I get the following errors.

mkrootdev expected fs options
mount: missing mount point
setuproot: moving /dev/failed no such file or directory
setuproot: error mounting /proc
setuproot: error mounting /sys
switchroot: mount failed No such file or directory
kernel panic

grub.conf looks like this. The commented out line didn't look right, so I made it look like the 2798 line... didn't work.

title Fedora Core (2.6.18-1.2849.fc6)
root (hd0,0)
# kernel /vmlinuz-2.6.18-1.2849.fc6 ro root=/dev/VolGroup00/LogVol00 rhgb quiet /dev/VolGroup00/LogVol00
kernel /vmlinuz-2.6.18-1.2849.fc6 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.18-1.2849.fc6.img
title Fedora Core (2.6.18-1.2798.fc6)
root (hd0,0)

initrd /initrd-2.6.18-1.2798.fc6.img

fstab looks like this... somehow it looked like an extra / mount point got in there, so I commented it out... didn't help

I had similar problems with 2849 but most of my trouble was focused on the problems it has with USB as this is how I get the keyboard and mouse control of the system. What little poking around I did do (which was quite exasperating and slow) indicated other problems, but I never got to them and the problems go away when I revert back to 2798. What I found really funny was that the "Load" in the system monitor applet was high (about 50% of the window, which is probably about 3.5) yet the CPU graph was indicating almost no activity, as was the network and disk monitors! I thought the system had locked up, but it hadn't. Perhaps this will be a clue for the devellopers.

Also, the USB interfaces seemed to work once they got started, however as soon as input stopped, it would take several seconds before they would respond again. That is, once you get I/O going, if you keep it going it continues to work ok, but if it stops there is a several second delay.

I also found the keyboard became an autorepeat keyboard and was sensitive to certain keys. It could just be their place in time (ie in my username) but it always seem to go into repeat on a certain key.

2798 fixed all of th problems, and in fact I'm currently working on one of the previously "broke" systems that was fixed only by rebooting and using Grub to load the old kernel.
