IBM Thinkpad T20, 700MHz selinux disabled, rhgb disabled On some kernels, X11 would fail to start some of the time. rhgb would run but when gdm started, sometimes I would not get a login screen, could not ping machine. If I did get to gdm login screen, its rock solid stable after that. Disabled rhgb - still was a problem sometimes, so rhgb was not at fault - but I left it disabled anyway. It is NOT a problem with knoppix, so its not a hardware issue. Virtual consoles also do not work in runlevel 5 (haven't tried others) kernel 2.6.11-1.1284_FC4 seemed better - virtual consoles still didn't work, but I seemed to have no problems booting to runlevel 5. If it still was a problem in that kernel, I just have been lucky. kernel 2.6.11-1.1287_FC4 - have not had a successful boot to runlevel 5 - happens every time I try, switching to 1284 in grub and it boots into runlevel 5 just fine.

AR5212 802.11abg NIC (rev 01) I do boot with acpi=force - I don't know if that's an issue or not. Interestingly, w/o acpi=force, when docked if xscreensaver comes on, I can't move external mouse to get the xscreensaver password box - acpi=force and I can. But that's the least of my worries, only mentioned in case it's an acpi issue I'm seeing.
