Constant OS Crashes with Newest ISO/New Kernel
Closed, ResolvedPublic


Since updating to the newer kernel my laptop keep crashing every 20 min with EXT4-fs error (reading directory lblock 0). I tried wiping the drive, recreating partitions, reinstalling Solus (Budgie, Gnome) but nothing seems to work.

After some digging I found this bug, which perfectly fits the description:

Before I try to play with boot parameters I wanted to report this as this will affect anyone with NVMe hard drive (I suppose specific brand/type? People reported it with DELL and Thinkpad laptops) who install Solus or update to newer kernel.

The crashes are random but sometimes it happens so fast I can't even perform an update in the software centre.

Anyone? I tried

I tried updating grub with nvme_core.default_ps_max_latency_us=5500 but when I try to do sudo update-grub I get
/usr/sbin/grub-mkconfig: line 232: /boot/grub/ No such file or directory

I can't use Solus for longer than 15 min, any advice would be really appreciated or else I would have to move to something with an older kernel or Ubuntu since the workaround above apparently works there.


To add a kernel parameter to boot you would need to add nvme_core.default_ps_max_latency_us=5500 to /etc/kernel/cmdline You will likely need to create this file

Afterwards, run sudo clr-boot-manager update to have that parameter added to the kernel configuration on boot.

But looks like this patch could be added to the kernel or backport the new version of the patchset, as there looks to be a couple of extra fixes

Have also looked at your other task. There's no comment as the attempts haven't worked so nothing to update.

Many thanks @sunnyflunk I will try the kernel parameter. No clue about kernel patches so will go with the cmdline.

As for the other issue, apologies, I was not aware any actions have been taken. Absolutely loving Solus and would prefer not to switch to other distro but the ASPS and R crashes are making it impossible to work. If there is anything I can do to help with R problem please let me know.

JGH1000 claimed this task.

The kernel parameter fixes the problem. Everyone using Samsung NVMe SSDs will have to put in manually though. Thanks for the instructions @sunnyflunk
