Soft Lockup with T5500 Processor on Kernel 2.6.30

Hi,

Today I've had a recurring error that is causing my system to lock up. My keyboard and mouse become unresponsive and the screen appears to freeze. I am forced to perform a hard reset after trying ctrl+alt+backspace, and ctrl+alt+delete with no response. I've used my Arch setup since September of 2008 without any prior major issues and I performed an upgrade yesterday and earlier today.

My /var/log/errors.log shows the following:

Jul  5 16:42:37 acer232 kernel: BUG: soft lockup - CPU#1 stuck for 61s! [X:5594]
Jul  5 16:43:42 acer232 kernel: BUG: soft lockup - CPU#1 stuck for 61s! [X:5594]
Jul  5 16:44:48 acer232 kernel: BUG: soft lockup - CPU#1 stuck for 61s! [X:5594]

My processor is a T5500 and I am running kernel version 2.6.30-ARCH.

My /var/log/everything.log shows the following:

I don't know how to interpret the above below where the modules loaded are listed. I'd appreciate any help at all that you can offer.

Re: Soft Lockup with T5500 Processor on Kernel 2.6.30

I too am having this problem. I found this on the kernel mailing list:http://lkml.indiana.edu/hypermail/linux … 02389.html.

So, try setting /sys/devices/system/clocksource/clocksource0/current_clocksource to acpi_pm and see what happens...

Re: Soft Lockup with T5500 Processor on Kernel 2.6.30

Basically it's a regression in 30 with the tsc clocksource. To enable it permanently, you can modify grub and add clocksource=acpi_pm to the kernel line.
