After the kernel update today to 5.14.21.150400.24.84.1 the system boots, but
due to constantly repeated amdgpu error the files /var/log/messages and
/var/log/warn grows up to gigabytes in a few minutes and the root file system
gets exhausted and no space is left on the device. switching back to the
previous kernel 5.14.21.150400.24.81.1 "solves" the issue.

GIT Branch: SLE15-SP4_EMBARGO
Distribution: SUSE Linux Enterprise 15
Name        : kernel-default
Version     : 5.14.21
Release     : 150400.24.84.1
Architecture: x86_64

/var/log/messages is full of errors like this
