Kernel Panic on Thinkpad X1-Extreme-Gen2 on Ubuntu 19.10

Asked by Hamish Marson

After updating an Ubuntu 19.04 installation (Brand new) a subsequent update to 19.10 results in a system that panics on boot

Same panic occurs when attempting an install of 19.10 from current ISO via USB stick

Kernel is 5.3.0-13-generic

Have photo of panic including Call trace. The Call trace ends up in tpm_read_log_efi

I suggest you report a bug. Eoan is not ready and not stable. It most likely won't be stable even a few weeks after release.

Awaiting progress on bug report. Have also replicated same or similar crash on other distros with kernel 5.2 or 5.3

Can you try kernel 5.3.0-17.18 or higher? Seems like it's the same bug as https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1845454 which is already fixed in 5.3.0-17.18.

Success. Thanks. A known bug with a fix via 5.3.0-18 (I guess it came through in the last few days? Previous kernel before updating today was 5.3.0-17
