I will upload it somewhere on request if it would help to actually see the process I went through here. The first time I booted an unpatched git kernel from 2.6.28-rc2 (2.6.28-rc2-00185-ge946217). This kernel locks up immediately upon printing the "Restarting system" message to the console. The second boot was a kernel from git, with commit 8fd14591 reverted, based on 2.6.28-rc2 with some of the git updates. This kernel reboots successfully. The third boot was done using the same kernel as the second boot. The "iow" command that was supplied in comment #5 was executed, and then a reboot was attempted. The result was that the kernel locked up the same as the first, unpatched 2.6.28-rc2 kernel from git did. When the iow command was run, the display read: # ./iow --addr 0xCF9 --width 8 --value 0x06 the value written into IO port 0xcf9 is 6 I then attempted the reboot, wherein it locked up after printing "Restarting system." Please let me know if any more information is needed. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
