Compaq Presario desktop using ubuntu 10.04 LTS with no ACPI installed. Same problem with messages.log maxed out. The continual logging bogs the system. If I edit the startup to include "acpi=off" or "pci=noacpi", the error stops logging, but NAT won't connect to the internet via eth0. Repeating log entries: Jun 11 10:25:51 timt-desktop kernel: [ 1308.823339] ACPI Error: Illegal I/O port address/length above 64K: 0x00400020/4 (20090903/hwvalid-154) Jun 11 10:25:51 timt-desktop kernel: [ 1308.823357] ACPI Exception: AE_LIMIT, Returned by Handler for [SystemIO] (20090903/evregion-424) Jun 11 10:25:51 timt-desktop kernel: [ 1308.823370] ACPI Error (psparse-0537): Method parse/execution failed [\_GPE._L09] (Node db80fd68), AE_LIMIT Jun 11 10:25:51 timt-desktop kernel: [ 1308.823422] ACPI Exception: AE_LIMIT, while evaluating GPE method [_L09] (20090903/evgpe-568)
Same problem with Fedora and Red Hat. Red Hat says they fixed it by "Truncate I/O addresses to 16 bits for Windows compatibility." Fedora says their source code fix is here: http://kerneltrap.org/mailarchive/git-commits-head/2009/4/5/5411984 ** Changed in: linux (Ubuntu) Status: Expired => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/475704 Title: Karmic desktop livecd constant kernel ACPI exception messages: AE_LIMIT, Returned by Handler for [SystemIO] 20090521 evregion-424 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/475704/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
