I have installed Karmic beta and had the first freeze today. Laptop was just sitting idle, don't know for how long exactly. Screen was black and no way to wake the laptop up again but to do a hard reboot (turn off-on).
One clue may be that the boot process complains of an unknown BIOS version: Acer Aspire 5100 v1.80... Will keep testing, but it seems the issue is still there. -- System freeze with ACER aspire 5100 https://bugs.launchpad.net/bugs/446274 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
