Resume from hibernate fails with kernel 4.12.3

Hi,
since the upgrade to kernel 4.12.3 resuming from hibernate fails on my Asus eeePC 1005PE.
Downgrading the kernel to v. 4.9.11 (or using the kernel from linux-lts) resolves the problem.

With kernel 4.12.3, at first, the boot/resume procedure seems normal (lots of disk activity) but roughly at the time when kernels <4.12 switch to graphics mode and show the plasma lock screen, kernel 4.12.3 simply reboots. Removing "quiet" from the kernel command line doesn't give additional info about the problem. Setting acpi_osi doesn't help.

I couldn't find anything related in the Arch bug tracker. Nevertheless, is this a known problem? Is there a workaround?

System is a 32-bit Arch with LVM on LUKS and Plasma as a DE.

Regards

Re: Resume from hibernate fails with kernel 4.12.3

I can confirm that this happened to me upon upgrading from 4.11.9 to 4.12.3.  The only entry from my log after I start hibernating and before I have to reboot is

 PM: Syncing filesystems ... 

This is what the log shows upon successful hibernation under linux-lts:

Seems to fail pretty early in the process, although the disk activity seems normal.  I am also running a 32-bit system (Dell Latitude D420).

4.12.4 might have a fix. See https://www.linuxquestions.org/question … ost5741416

Thanks for the tip! But unfortunately the 4.12.4 kernel I installed from testing doesn't solve the resume problem for me.
There is a difference, though: while 4.12.3, instead of showing the lock screen, simply rebooted, 4.12.4 hangs completely.

Any chance you can use 'git bisect' to find the offending commit?

No. I don't really have an idea how to do that.

Although that PKGBUILD is targeted at bisecting 4.9 to 4.10 it should be readily adaptable to 4.11 to 4.12
