I just experienced this problem on a coldboot (although I was too impatient to wait the 5-10 minutes to see if it recovered). Adding the blacklist ITCO_wdt fixes the hanging issue.
Running Intrepid , uname 2.6.27-4-generic i686 I updated last night. It coldbooted fine this morning, but doing a cold boot this afternoon had failed after a few installs and an update. I have attached the portion of /var/log/apt/term.log that contains the updates/installs between working coldboot and non-working coldboot. ** Attachment added: "term.log" http://launchpadlibrarian.net/18577480/term.log -- [hardy] iTCO_wdt: failed to reset NO_REBOOT flag, reboot disabled by hardware https://bugs.launchpad.net/bugs/218357 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
