Seems related to the following upstream bug: http://bugzilla.kernel.org/show_bug.cgi?id=12376
And the karmic kernel indeed already contains the patch. It would be interesting if you tested booting with "acpi_enforce_resources=lax" as noted in the commit message. ogasaw...@emiko:~/ubuntu-karmic$ git log 7e90560c50f754d65884e251e94c1efa2a4b5784 commit 7e90560c50f754d65884e251e94c1efa2a4b5784 Author: Luca Tettamanti <[email protected]> Date: Mon Mar 30 00:01:27 2009 +0200 ACPI: acpi_enforce_resource=strict by default Enforce strict resource checking - disallowing access by native drivers to IO ports and memory regions claimed by ACPI firmware. The patch is mainly aimed to block native hwmon drivers from touching monitoring chips that ACPI thinks it own. If this causes a regression, boot with "acpi_enforce_resources=lax" which was the previous default. http://bugzilla.kernel.org/show_bug.cgi?id=12376 http://bugzilla.kernel.org/show_bug.cgi?id=12541 Signed-off-by: Luca Tettamanti <[email protected]> Acked-by: Pavel Machek <[email protected]> Acked-by: Jean Delvare <[email protected]> Signed-off-by: Len Brown <[email protected]> ** Bug watch added: Linux Kernel Bug Tracker #12376 http://bugzilla.kernel.org/show_bug.cgi?id=12376 ** Bug watch added: Linux Kernel Bug Tracker #12541 http://bugzilla.kernel.org/show_bug.cgi?id=12541 ** Changed in: linux (Ubuntu) Status: New => Incomplete -- [karmic] ACPI I/O error during boot https://bugs.launchpad.net/bugs/422680 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
