Hi all
Anyone else experiencing hard lockups since approx December 2023 on Ubuntu / Kubuntu?
I've got the same hardware, there's no hardware changes. I suspect it might have been a kernel / driver upgrade, I did pull some info from dpkg logs that said 12th December
2023-12-12 09:47:49 upgrade linux-image-generic:amd64 5.15.0.89.86 5.15.0.91.88
Does this mean that I went from version 5.15.0.89.86 to version 5.15.0.91.88? How does one revert back to test for stability?
When the lockup occurs, it seems that all graphics processes freeze, mouse freezes. No blinking lights on the keyboard. I vaguely remember that sometimes I can switch to one of the other terminals (what used to be tty2-6) but nothing seems to respond.
When I tried to do this a couple of weeks ago, it seemed to be wanting to remove lots of things, and I never proceeded.
sudo apt-get purge linux-image-5.15.0-91-generic
I had journal logging to Konsole back then and saw some messages (I have a phone on my phone) about PCIe Bus Error, BadTLP and BadDLLP and timeouts, Uncorrected fatal errors with AER, and nvme0: frozen state and PCIe bus error.
How does one even know if their NVME drive is failing? AFAIK, smartctl doesnt work on them in the same way it does on spinning drives. Or is this a kernel bug?
Thanks, Srdjan
