Kernel oops in cgroup_get sinc July #314

Open treepleks opened 6 years ago

treepleks commented 6 years ago

It all started on the 7th of July this year (4.9.35). All the kernel updates since have shown the same issue. After some time (less than few hours), my XU3 kernel oopses and networking stops working. I then have to reboot it, the hard way.

NB: My Archlinux XU3 acts as a NAS and has a USB3 Gigabit Ethernet/Hub connected to its USB3 port.

Here are some of these oopses. Last version (Linux odroidule 4.9.50-3-ARCH #1 SMP PREEMPT Sat Sep 16 05:55:29 UTC 2017 armv7l GNU/Linux) does it too.

I downgraded to 4.9.34 and rock stability seems to be back...

I'm getting similar issues on my XU4 on ArchlinuxArm (4.9.50-3-ARCH), which I also use as a NAS, among other things.

Despite getting this output in dmesg (usually after or during boot, but sometimes it does it occasionally later too), I can't actually observe any detrimental effects, so if it is "doing" anything it must be behind-the-scenes.

@treepleks It's a great device, very useful piece of kit. :)

Can you try with the current kernel version from this github?

aphirst commented 6 years ago

@mdrjr I don't have a build system set up for the moment. If I have chance, I'll try to build .52 or -git later today. Otherwise, it'll have to be once .52 reaches the ArchlinuxARM repo.
