My 600E continues to work fine under kernel 2.6.27.12-170.2.5.fc10.i686. All subsequent kernels I have tried, including the most current (kernel 2.6.27.29-170.2.78.fc10.i686) are really ragged, failing to complete the boot process about 40% of the time in a variety of ways at a variety of points in the boot process. I generally can find no trace of the problem in /var/log/messages or dmesg. The intermittent and variable nature of the problem makes formulating a bug report difficult. As an example, the current kernel (or startup scripts) has failed a few times immediately following startup of sm-client. The following console messages appear (I have manually transcribed this output, so it may contain typos, and I have edited out large portions of the text, but, since I have no idea what this information means, I may have deleted important information - sorry):

No further console ouput occurs following this. The service that starts immediately following sm-client is crond.
Errors also occur in a similar fashion but at other points in the execution of startup scripts. Also, sometimes boot freezes after login of a user but before all the icons appear on the desktop. And sometimes starting Firefox causes a Firefox pid to be created, but firefox never actually opens a window, and the process can not be killed with "kill -9" (it's stuck in the kernel?). So, this is a very unsatisfactory stew of problems. The fact that the old kernel continues to work fine suggests that failing hardware is not the cause, I guess. Are you having similar problems? Can this problem be better defined somehow?
Thanks for considering these questions.
Edit: And sometimes a kerneloops is generated such as:

More info: kernel 2.6.27.29-170.2.79.fc10.i686 is just as bad - kernel oopses, kernel panics, boot freezes. Awful. memtest completes a pass with no errors. Resetting the BIOS and re-disabling Quickboot has no effect. kernel 2.6.27.12-170.2.5.fc10.i686 continues to work fine. All recent kernels work fine in my hands on a home-brew AMD Duron desktop and a Dell Inspiron 7500, so this problem is somehow Thinkpad-centric. Strange.
More info: kernel 2.6.29.6-97.fc10.i686 (from updates-testing repo) fails to boot about 60% of the time, also at a variety of points in the boot process. Here's an example of a problem:

Just for fun I tried booting with the wlan pcmcia card removed => no improvement.
It's difficult to formulate a coherent formal bug report out of this mix of troubles. Anything else I can do to try to characterize the problem? Am I the only one encountering such problems?
More info: Adding "boot_delay=5" to kernel line in grub.conf does not help.
