This bug should be fixed by the following patch:
--
From: Kevin Hilman
Date: Wed, 30 Sep 2009 17:35:53 + (-0700)
Subject: CPUidle: always return with interrupts enabled
CPUidle: always return with interrupts enabled
In the case where cpuidle_idle_call() returns before changing state
due to a need_resched(), it was returning with IRQs disabled.
This patch ensures IRQs are (re)enabled before returning.

This error was also reported in bug #451553 but I'd like to keep them separate. There were a whole lot of errors mentioned in the other bug that seem to only happen when booting from USB. This one seems to happen, even after installation and booting from sata. ** Changed in: linux-mvl-dove (Ubuntu) Importance: Undecided => Medium ** Changed in: linux-mvl-dove (Ubuntu) Status: New => Triaged -- WARNING: at arch/arm/kernel/process.c:174 cpu_idle+0x8c/0xa0() https://bugs.launchpad.net/bugs/458533 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
