@metak yeah I saw that thread. They seem to conclude that it's something related to LVM, and I am indeed using LVM on LUKS, though for me the issue only happens on linux-clear. The screen is black with a blinking cursor and eventually (maybe 90 seconds, I should actually time it) it says something about failing to unmount oldroot and then it reboots.
Edit: thanks @metak. I won't spam here anymore. Nice to know I'm not alone and that someone has even reported it upstream. For reference, here is the message that is spammed after the cursor blinks for ~90 seconds and it finally reboots:
[ 116.123456] sd-umoun[1040]: Failed to unmount /oldroot: Device or resource busy
[ 116.123456] sd-umoun[1041]: Failed to unmount /oldroot/dev: Device or resource busy
[ 117.123457] reboot: Restarting system

Issue handling
Please only submit issues in the package's repository if they aren't bug reports about the package or help requests. Please keep them to the AUR only. This prevents unnecessary signups.
Updates
I usually publish updates 0-3 days after a kernel release, depending on how busy I am.
If I however get wind of security-relevant updates or any vulnerabilities I will try to update the kernel as soon as possible and write a comment about the vulnerability/update. So make sure to subscribe to this package's comment mailing list.
PKGBUILD environment variable customization
The PKGBUILD file supports customization via environment variables. Here's a list of all of them:
-
_makemenuconfig: Invokesmake menuconfig(ncurses-based default configuration menu) before compilation starts-
_makenconfig: Invokesmake nconfig(ncurses-based nicer configuration menu) before compilation starts-
_makexconfig: Invokesmake xconfig(X11-based GUI configuration menu) before compilation starts-
_use_current: Will use the configuration of the running kernel, if the running kernel is compiled withIKCONFIG_PROC-
_optimize_defconfig: Applies package maintainer-picked configuration changes to your defconfig. Only takes effect with_use_currentbeing enabled-
_copyfinalconfig: Copies the final kernel configuration into the repository root askconfig-newbefore compilation starts-
_localmodcfg: Only compiles modules found in modprobed-db's database (which decreases compilation time and kernel size)-
_use_llvm_lto: Compiles the kernel with LLVM instead of GCC. Should work, if not open an issue-
_subarch: Specifies the subarchitecture to compile for (see the PKGBUILD file for a list of all subarches). Default is41/MGENERIC_CPU(Generic x86-64), which is compatible with all amd64 processors. Must be a number or subarch name-
_subarch_microarch: Specifies the microarchitecture to compile for. Only applies to and is required by theMGENERIC_CPUsubarch. Must be a number between1and4(click for more information)-
_debug: Force enables debug options when set toy, force disables debug options when set tonor uses the config defaults when unsetAll of these variables just need to be set for them to apply, except for
_subarchand_debug. For more information please check their documentation inside thePKGBUILDfileGPG errors
If makepkg complains about invalid PGP keys, try running this command first:
gpg --locate-keys torvalds@kernel.org gregkh@kernel.org sashal@kernel.org benh@debian.org. This command only needs to be executed once.Build tool
If you want a dead simple way to compile this package, you can try out my build tool. It includes a few no nonsense changes to the kernel configuration and allows you to configure the PKGBUILD file in a simple manner and decrease build time. And if you don't want that, using
makepkgas-is works fine too.
