linux 4.9-1

kernel panic on boot. 4.8.13-1 works ok.

This happens even before the video resolution has been reset.
Some acpi calls are visible in the stack trace on the screen.

This is on a Toshiba Satellite L655, with a Pentium P6200, Intel chipset and graphics.

I don't know what else I can say at this point. Let me know if there are additional tests to try.

This task depends upon

Ok, I tried booting with acpi=off on the command line, and yes, it does then boot without crashing, though this makes a mess of things. For instance, the screen resolution is not set, and the network interface names change, breaking network init.

Also panics with acpi=ht.


"If acpi=off works and acpi=ht fails, then the issue is in the ACPI table parsing code itself, or perhaps the SMP code."

BTW, Toshiba has a special module, toshiba_acpi.

Documentation/kernel-parameters.txt makes no mention of "acpi=ht", so that may not work or mean anything any more.

Seems to be the same as  bug 52246  ; will try to boot using acpi=off and report asap.

There are no acpi updates in linux 4.9.1, and so the kernel panic on boot is still there.

And not in 4.9.2 too. By the way, with acpi=off I can get it boot, but there is no working xorg display :(

Can we revert this patch and see if it boots correctly?

Found on this forum thread :

Another upstream bug closed as unreproducible :

Or apply / revert the patch found in this bug report?

Edit : Applied it, build a kernel and still no luck :(

Reverting the commit seems to work, at least for my intel based laptop.

Looks like there could be a patch for linux 4.10-rc4 :

I see linux 4.10.1-1 working normally on the Toshiba Satellite L655. says "it is in v4.9.6 and newer."

Thanks Frederic.
