Hi,
A Gentoo user reported a 2.6.16 regression at http://bugs.gentoo.org/129011
In a nutshell, ACPI worked in 2.6.15, and breaks in 2.6.16 and the
/proc/acpi interface is not present. Here are the relevant looking
messages from dmesg:
ACPI: SCI (IRQ0) allocation failed
ACPI Exception (evevent-0167): AE_NOT_ACQUIRED, Unable to install System
Control Interrupt handler [20060127]
ACPI: Unable to start the ACPI Interpreter
evxfevnt-0134 [06] disable : ACPI mode disabled
ACPI (utalloc-0862): No outstanding allocations [20060127]
ACPI Exception (utmutex-0257): AE_BAD_PARAMETER, Thread 1 could not
acquire Mutex [6] [20060127]
ACPI Exception (utmutex-0257): AE_BAD_PARAMETER, Thread 1 could not
acquire Mutex [6] [20060127]
Full dmesg can be found at
http://bugs.gentoo.org/attachment.cgi?id=84551&action=view
This bug is already fixed in 2.6.17-rc1. Does anyone know offhand which
patch fixes this? I'd like to backport the fix and also submit it for
the -stable branch.
Thanks,
Daniel
