Subject: Linux 5.13-rc6 regression to 5.12.x: kernel OOM and panic during
kernel boot in low memory Xen VM's (256MB assigned memory).
L.S.,
I just tried to upgrade and test the linux kernel going from the 5.12 kernel series to 5.13-rc6 on my homeserver with Xen, but ran in some trouble.
Some VM's boot fine (with more than 256MB memory assigned), but the smaller (memory wise) PVH ones crash during kernel boot due to OOM.
Booting VM's with 5.12(.9) kernel still works fine, also when dom0 is running 5.13-rc6 (but it has more memory assigned, so that is not unexpected).
The 5.13-rc6'ish kernel is a pull of today, tried both with and without last AKPM's patches, but that
makes no difference.
Below are stacktraces from a few of the crashing VM's.
Attached is the kernel .config
Any pointers ?
