I'm also affected by this issue on this setup: Acer Aspire One D150 BIOS: 1.05 (latest) uname -a: Linux yogsothoth 2.6.28-15-lpia #49-Ubuntu SMP Tue Aug 18 16:21:46 UTC 2009 i686 GNU/Linux lsb_release -sd: Ubuntu 9.04
During boot sometimes it locks, and when pressing any key (Ctrl is enough) it continues. (this means that the OS waiting for an interrupt). However, after a couple of minutes, the system completely hangs, and I must brute-power-off it to recover from the crash. The only way to boot is to enable "acpi=off" in /boot/grub/menu.lst, but this way there are other issues: - Obviously no standby option, and you must hold down the power button on shutdown; - No more bluetooth by pressing the BT key - HOT temperature!!! I think it could be dangerous! - no CPU frequency scaling, so the battery decharges fast - Ctrl+S in any program doesn't work (!!! this made me laugh :-) ) I've also read on other bug reports that it should be a BIOS issue, that can be fixed by loading a custom DSDT file. I attach some logs and my dsdt file. ** Attachment added: "acer-aspire-one-dmesg1.txt" http://launchpadlibrarian.net/31004574/acer-aspire-one-dmesg1.txt -- ACPI: EC: missing confirmations, switch off interrupt mode. https://bugs.launchpad.net/bugs/284263 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
