soft lockup: CPU# stuck, opensuse 11.4

Hello,

This looks very similar to what is described in this thread

11.4 Boot Freeze

That is there is a

BUG: soft lockup - CPU#0 stuck

message and the boot hangs.

The modprobe/migration codes are not identical with the linked thread. I’m stuck with CPU#0 at [modprobe:138] and #1 stuck at [migration1:8]. Generally after 61 or 63s.

This is a zypper dup from latest 11.3.

The machine boots with acpi=off, luckily. But I’d like to have it all working.

The forum says I can’t post attachments; hwinfo output seems a bit copious to quote inline. But I’d be happy to provide any additional info obviously.

Basic HW is Core2 E8400, Intel G41 chipset. Cheap ASRock MB.

TIA,

It may be helpful to tell use what hardware this occurs on.

It’s a white box. Core2 E8400 3 GHz, ASRock G41M-S MB (Intel G41 + ICH7 Chipsets). 2 Gig of Ram. That’s it. There’s a Sata disk of some sort and a usb keyboard/mouse.

You might check for BIOS updates for that board.

Also since this is a desktop acpi is not as important as on a laptop.

OK I went through the exercise and updated the BIOS. No change.

This computer doesn’t really ever get turned off (except weekends!) so ACPI does have a purpose. I’d like to have everything working correctly at 11.4 level. For 11.3 I had to run in safe mode to avoid panics. (Turning acpi off helped but did not eliminate that problem).

I’m guessing this is the same as Bug 679178.

Dear Friends,

I have a Samsung R528 Laptop. I had exactly the same problem after upgrading to 11.4. This problem might possibly related to KMS feature of the kernel
The problem was solved after adding the boot option ACPI_OSI=“Linux”
