5.10 is fine with same rootfs

vineetgarc commented 3 years ago

So it seems there are a couple of issues which surprisingly the inhouse regression jobs have not caught (perhaps they went away for holidays too).

First issue is snafu in generic signal handling changes: 53855e12588743ea128 ("arc: add support for TIF_NOTIFY_SIGNAL") which I didn't spot at the time of review. Fix will likely make it into 5.11-rc3: http://lists.infradead.org/pipermail/linux-snps-arc/2021-January/004729.html

The 2nd is no console output in a devtmpfs based Buildroot init system due to upstream 757055ae8dedf5 ("init/console: Use ttynull as a fallback when there is no console"). This has been reported to mailing list too http://lists.infradead.org/pipermail/linux-snps-arc/2021-January/004728.html

vineetgarc commented 3 years ago

Fixes for both the issues: arc: add support for TIF_NOTIFY_SIGNAL and Revert "init/console: Use ttynull as a fallback when there is no console" have been merged in released 5.11-rc3

Verfified that 5.11-rc3 boots fine.
