Unstable LTS kernel 4.13

[Josep Pujadas-Jubany]

At job, after upgrading many Lubuntu 16.04 LTS 64 bit systems from 4.10 to 4.13 they are (most of them) unstable.

Acer TravelMate B117-M (SSD disk) freeze at boot or show errors at startup such:

unexpected irq trap at vector

similar to https://forum.manjaro.org/t/manjaro-kernel-4-13-unexpected-irq-trap-at-vector-e3-error/30942

At home (no signed kernel, old machine) my VirtualBox freezes also the machine, as explained at https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1736116/comments/14

Absolutely! I got errors on my Desktop PC with Nvidia GPU during the upgrade when it was building modules for the graphics card. When I updated my laptop with intel graphics, things were not stable (graphics-wise). Reverting to kernel 4.10.0-xx things are back to normal. Had to remove on both computers the newer kernel and anything related to HWE

Terrible upgrade, I see many posts and bug reports in the last hours with everyone having similar issues...

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

4.13.0-30.33 available with dist-upgrade

We installed it on 12 machines. It seems to be stable.

[Josep Pujadas-Jubany (jpujades)]

I'm sorry!

dist-upgrade on our 16.04 LTS HWE systems installs 4.13.0-31

It seems to be estable, as I said.

[Josep Pujadas-Jubany (jpujades)]

Some of our Acer TravelMate B117-M (SSD disk) still having problems with 4.13.0-31

They freeze at boot or show errors at startup such:

unexpected irq trap at vector 73

Updated BIOS to 1.13 & 1.15 doesn't hel for Acer TravelMate B117-M (SSD disk).

[Josep Pujadas-Jubany (jpujades)]

Curiously, if I turn off the system, connect/disconnect the battery (battery reset hole at the bottom of the laptop) and turn on the system, NO errors.

At next boot, errors reappear.

It seems to be related with https://bugzilla.kernel.org/show_bug.cgi?id=194945#c73

I can see also bad interrupts for chv-gpio

No more IRQ errors with kernel 4.14.15-041415-generic

Tested on HP Convertible x360 11-ab0XX with same results.

4.13.0-32.35~16.04.1, latest 16.04 LTS HWE kernel still have the problem

See apport-collect results before this message. Thanks!

[Po-Hsu Lin (cypressyew)]

Hello,
do you still experiencing this issue with the latest HWE kernel (4.15) on Xenial?
Thanks

[Josep Pujadas-Jubany (jpujades)]

Our systems are stable with later kernels:

uname -a
Linux xxxxxx-lubuntu 4.15.0-47-generic #50~16.04.1-Ubuntu SMP Fri Mar 15 16:06:21 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

At home (were I have virtualbox) I switched to Oracle package to solve the problem and I didn't revert my installation to the 16.04 package:

dpkg -l | grep virtualbox
ii virtualbox-5.2 5.2.28-130011~Ubuntu~xenial amd64 Oracle VM VirtualBox

Thanks!

[Po-Hsu Lin (cypressyew)]

OK!
Thanks for the feedback, I am gonna close this bug.
Please feel free to open a new report if you have encountered any issue.
