Hi, it sometimes happens to me that X completely locks up, while the machine is still alive on the network. This is on F14, untainted kernel, nouveau driver, no 3D used, KDE desktop on a 32-bit machine with 8GiB RAM and PAE kernel. It typically happens when something is going to be drawn on the screen (a window pops up or virtual desktop change). I would like to open a bug, but I'm not able to attach any kind of usable log; dmesg says nothing, all I can say is that the screen remains frozen (including the pointer), the X server and the kernel keep doing some "SIG ALRM" stuff and any attempt to access the X server stalls the command (xrandr or xset, for example), in a Ctrl-C responsive way. This is happening on different kernel revisions. This laptop is perfectly stable and it sometimes takes a few weeks to show the problem (using suspend during the night). If I do a fresh reboot there is a high probability of a lockup in a mater of minutes/hours. Just as if there were lucky and unlucky reboots (important stuff being placed in memory areas which is easily corrupted?). Another data point: this laptop sometimes fails to suspend properly (remains frozen). In any case the last frozen-X event happened today before any attempt to suspend, so I can not blame the BIOS and ACPI parts.
