temporary fix: after some online reading, I tried the solution described here:
http://www.vmware.com/community/message.jspa?messageID=332390 In my case, the BIOS of my machine controls the fan, and upon boot up, when ACPI kicks in, the fan shuts off. I edited /boot/grub/menu.lst and found the line for my kernel and added acpi=off noacpi to the end of that. so mine looks like: title Ubuntu, kernel 2.6.17-11-386 root (hd0,1) kernel /boot/vmlinuz-2.6.17-11-386 root=UUID=0a5a4656-cf6d-4dc0-acd9-25908ebd2177 ro splash acpi=off noacpi initrd /boot/initrd.img-2.6.17-11-386 savedefault boot (end grub menu) it goes without saying this isn't the definitive cure for this problem, but my fan is running. ** Attachment added: "output of dmesg after fix" http://librarian.launchpad.net/6991602/dmesg.log -- edgy shutdown unexpected https://launchpad.net/bugs/93243 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
