kernel-2.6.27-0.382.rc8.git4.fc10.i686: seems to crash on boot. Booting to an older kernel (kernel-2.6.27-0.352.rc7.git1.fc10.i686) works. I think the problem is actually that I cannot see any error messages at all because the screen does not scroll as new text is printed, nor does it clear. i.e. once the screen is full the text seems to be printed behind the existing text. With the older kernel it is at least printed over the existing text and is so slightly visible. I have an encrypted disk, Entering my password does not help.
it might be more readable if you use a framebuffer console. Try booting with vga=791 (or if that fails, vga=1 at least should work).
791 doesn't work, 1 at least boots but doesn't help either: I still can't see anything useful. I see "Creating initial device nodes" at the bottom of the screen, then something about VIA padlock at the top, then "input: ImExPS/2 Generic Explporer Mouse" (where "input:" is the new text") Typing the password does nothing. Holding enter does nothing. Ctrl+Alt+Delete prints "stopping md devices" then reboots.
2.6.27.4-47.rc3.fc10.i686 works now.
