Question Strange message on Fedora 7 bootup , also Firefox problem


A short while ago I updated my F7 system. I noticed that it was removing a kernel and then installing a different kernel. I rebooted and noticed that logical volume management failed. I tried rebooting again with the i switch so the message wouldn't just fly past. But there was no clue, just the failure notice. The new kernel is 2.6.22. ???( I didn't write it down- sorry) Everything seems to work OK but the message bugs me. Does anyone know what this is all about?

On another note, every so often when I close out Firefox it logs me out of the Linux session. Seems to happen when I have multiple tabs open. Anyone know what this is?

Thanks in advance for any responses.

Question 1: you can see warning messages that passed by at boot time via
the "dmesg" command or by looking in /var/log/messages. After a while,
stuff in dmesg will fall off the end, it depends on how big the ring
buffer is set and how many messages are going into it.

dmesg - print or control the kernel ring buffer

Question 2: no idea about firefox doing that, do you mean Gnome/KDE desktop
totally goes away and you're at the text console?

Did it actually remove the old kernel or does GRUB give you the option of which kernel to boot ? If you still have the option to boot the old kernel (which I would hope!), you might try booting it and see whether or not you get the error. If you don't get the error with the old kernel but do with the new kernel, you can google on the error message and the kernel version and see if you can find out anything.

Question kernel problem went away, firefox still a puzzle.

The old kernel is still listed in grub and the new one is the default. Whatever was causing the message the logical volumes are there and the message no longer displays on boot. I didn't make any changes and have no clue why I got the message or why it went away, since despite it I always had my logical volumes. I guess the original cause will remain a mystery.

As for my firefox issue, I mean that I am immediately dumped back to my logon screen. It does not happen all the time. Seems to happen when I close firefox with multiple tabs open, but not always. The next time I open firefox I get a message saying that my session unexpectedly ended and asks if I want to restart the old session or open a new one. So far I haven't lost any data since usually nothing else is running when I am surfing the web, but I assume lost data is a possibility if any output buffers have not been cleared when this happens. I am unable to repeat this at will so I can't really zero in on the actual problem. Has anyone else experienced this action?

Re your LVM problem: Since the problem seems to have disappeared, it might indicate a hardware problem with the drive(s) on which he LVs reside. If you're using a desktop system, the most common cause of such problems is oxidation in the cable connections between the drive(s) and the mother board. Simply unplugging the connectors and plugging them back into the same place will usually fix the problem -- until more oxidation develops.

If your drive(s) are S.M.A.R.T.-capable, consider installing smartd to report any self-monitoring problems in the hard drive(s).

Re your Firefox problem: Try running firefox from a terminal window to see if any error messages are being generated. Another thought look at /var/log/Xorg.0.log to see if there's any clue there about why the X session terminated.
