Summary: powersaved causes a segfault in the kernel
Product: ACPI
Version: 2.5
KernelVersion: 2.6.24.3
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Processor
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
Latest working kernel version: unknown, worked with 2.6.22.18
Earliest failing kernel version: unknown, occurred at 2.6.24.3
Distribution: openSUSE 10.3
Hardware Environment:
* CPU: AMD Athlon 64 X2 5200+
* motherboard: ASUS M2N32-SLI Premium (NVIDIA nForce 590 SLI chipset)
* RAM: 4GB
Software Environment:
* openSUSE 10.3
Problem Description:
I have installed a vanilla 2.6.24.3 kernel (because the default openSUSE 10.3
kernel does not support motherboard sensors and on-board sound card); at boot,
it produces the following segfault message. The boot normally continues and the
system appears normal otherwise.
