Acer Aspire 3 (A315-41-R2GU) Laptop doesn't boot on Ketrnel 4.18.x where x > 5
Closed, ResolvedPublic

Description

HW specs can be found here: https://www.acer.com/datasheets/2018/4876/A315-41/NX.GY9EG.016.html

When trying to boot I get spammed by watchdogs message informing of a soft lock (CPU# stalled for ~22s).
I tried changing the recently changed radeon boot parameters back to how they were for the 4.18.5 kernel entry that works, doesn't change anything for me.

Some later kernels might also work but the first one after .5 I tried was .14 and that already didn't work.

Sorry about the sparse report, I have no idea where I should start troubleshooting this.

dmesg output from the failed boot would be helpful

I'm bad at kernel debugging. The dmesg log is not being persisted on these failed boots, meaning journalctl -k -b -1 shows me only the last successful boot on the .5 Kernel.

How can I get that log?

By running dmesg
