same problem here, Toshiba AX/940 LS. Suspend and hibernate can freeze the machine completely Power button does turn it off, but when pressed back, the box returns to the state of coma and nothing wakes it up. It is necessary to disconnect AC and take out the battery to get it back to life.
What is worse, it happened also once or twice when the system crashed during shutdown. -- Suspend / Hibernate broken (IBM Thinkpad T21) https://launchpad.net/bugs/52638 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
