IBM X31, kernel oops with >2.6.3-1.116 unless acpi=off
Last modified: 2007-11-30 17:10:37 EST
Description of problem:
Kernel oops at boot.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. boot a kernel newer than 2.6.3-1.91 (I did not necessarily have all
rawhided kernels after 91, but 2.6.3-1.116 has the problem)
2. be sure not to have 'acpi-off' in the kernel line
3. watch it oops
Twofold (full trace attached):
ACPI: Found ECDT
ACPI-0180: *** Warning: The ACPI AML in your computer contains
errors, please nag the manufacturer to correct it.
ACPI-0183: *** Warning: Allowing relaxed access to fields; turn on
CONFIG_ACPI_DEBUG for details.
drivers/acpi/ec.c:357: spin_is_locked on uninitialized spinlock dfece7c8.
Unable to handle kernel paging request at virtual address 80315aa0
acpi=off solves the problem, but as the X31 is quite widespread
internally, it would be a nice show off when on-site if ACPI worked
The ACPI warning also happened on 2.6.3-1.91.
As there was an LVM change after 2.6.3-1.91, ging back to that version
to do testing is painful. (I'm not sure if -91 did not have acpi
disabled by default)
Is there a chance we can get IBM to fix their ACPI AML?
