Hello,

I have the same error as follows - these lines begin at line 438 of the file, which is nearly the end of it.

[ 117.926535] Marking TSC unstable due to: cpufreq changes.
[ 117.934315] Time: acpi_pm clocksource has been installed.

[ 118.286247] Clocksource tsc unstable (delta = -179973678 ns)

When I added clocksource=acpi_pm to the menu.list entry for my newest kernel Ubuntu 8.04.1, kernel 2.6.24-22-generic, and rebooted, I was treated to a desktop where I was unable to get the drop down menu panel to drop down where I could use it, and the title bars and status bars of all applications were missing. I tried ALT-F2 for the Run command dialog, but that wouldn't come up, and ALT-F1 would not make the menu show either.

I was able to start a File Browser by clicking the Wine folder on the desktop, and from there was able to start a root terminal and capture the output of dmesg to file. Here is the same section from that file as is shown above from my more or less normal boot. - These start at line number 446 in the file.

[ 125.496519] Marking TSC unstable due to: cpufreq changes.

I did find this line at line 238 of the file, which makes me wonder why TSC still tried to install later.

[ 26.594400] Time: acpi_pm clocksource has been installed.

I then removed the clocksource=acpi_pm from the menu.list file, and had to use the power button to shut down, and restart the computer. On this boot it came up normally again.

I have been having problems with every fifth boot or so leaving me in the condition that the menus will not drop down out of hiding, ever since I updated to this kernel. Once in a while it will happen on two boot ups in a row, and I will then boot to the next previous kernel which works right all the time.

I am attaching the output of the dmesg command for the boot up where the menus refused to drop down.

Thanks for any help you can be, Ray Parrish
