Since upgrade to linux-aarch64-5.8.0-1-aarch64.pkg.tar.xz + linux-aarch64-chromebook-5.8.0-1-aarch64.pkg.tar.xz, my Asus C101PA Chromebook no longer starts when I press Ctrl+U on the boot screen to boot from SD card. It just beeps, shows black screen for a third of a second, and returns to the developer mode boot screen - no messages whatsoever about what is wrong. Is there any way to get some information about what failed?
Booting into ChromeOS (Ctrl-D) works, and from there I managed to downgrade to 5.7.8-1 from my /var/cache/pacman/pkg, which boots fine.
Any idea why, and what changed? I see only changes to the kernel config in the PKGBUILD, which seem to be the typical "make oldconfig" stuff. A very obvious change though is that the old kernel package has a .kpart file of 29.3 MiB and the new one is much larger (35.7 MiB). My kernel partition is 128 MiB though (resized from 32 MiB after the -rc kernel broke the 32 MiB barrier before, but that one still booted fine). So could it be that there is a limitation to kernel size on this device and it's been broken of course just a guess, as I see no error message at all, just the beep? If so, any plans for a workaround that is "more convenient" than me compiling my own kernel with a trimmed down config on every update?
FYI, the current linux-aarch64-chromebook-rc fails for me the same way, too.
