Just as a heads-up: This particular issue is related to this patch in the Debian kernel package: > https://salsa.debian.org/kernel-team/linux/-/blob/master/debian/patches/bugfix/powerpc/fbdev-offb-Update-expected-device-name.patch?ref_type=heads Removing this patch unbreaks the console on PowerMac G5. I could also reproduce this issue with the latest ppc64el image on PowerKVM: > https://cdimage.debian.org/cdimage/daily-builds/daily/current/ppc64el/iso-cd/debian-testing-ppc64el-netinst.iso Here is a video demonstrating the issue: > https://people.debian.org/~glaubitz/debian-bug-1033058.mp4 And here is the corresponding bug report: > https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1085949 This issue can be easily reproduced with QEMU. Aditi Mishra (CC'ed) is trying to reproduce the issue as well, but so far has been unsuccessful. Adrian -- .''`.
