Guys, if you have any idea about what i could try, please tell me.
The only things i have done so far is to try the various workarounds that are proposed in the other bug reports related to kernel panic.

Hello, this has become a serious problem (

After a pacman update yesterday, multiple desktops, laptops (including many models of Dell XPS) and servers have failed to boot in our university.

We get this early panic (just after "decompressing linux, booting kernel") and the CPU halts:

"PANIC: early exception 06 rip 10:ffffffff81456a10 error 0 cr2 0"

Please fix it!!!!

On Dell XPS l701x laptop you can fix the kernel panic by disabling wireless AND external usb in bios.

Thanks for that!
We have anyway downgraded to 3.1.

Also I'm sorry, the panic on non dell laptops was different and associated with motherboard.

Waiting for the next kernel release.

I confirm that kernel 3.3.2 does NOT solve the problem (as I'm debugging it with that version).
However, I've just found a way to patch 3.3.2 to allow the boot. However, I'm awaiting validation from an kernel expert as I'm not an expert at all.

All info is located in the upstream bug report:

I can confirm that the new patch works perfectly with the mainline Arch kernel (3.3.2) on the Dell XPS L501x.

Patch located here:

thanks! patch works with 3.3.2-ARCH on dell xps L501x and L701x
Comment by Valère Monseur (valr) - Sunday, 22 April 2012, 07:02 GMT
Yep, patch is ok.

@tpowa & brain0, will you integrate the patch in the current kernel or just wait for the new upstream release?

I'm not seeing the patch in v3.3.3...we may have to wait until v3.3.4
