The kernel fails to decompress at boot, taking you back to the grub menu. It is difficult to catch boot messages that early, but I believe that the kernel is failing to decompress properly if compressed with lbzip2 Reproducible: Always Steps to Reproduce: 1. Build app-alternatives/bzip2[lbzip2 -pbzip2 -reference] 2. Build sys-kernel/gentoo-sources with CONFIG_KERNEL_BZIP2 3. Reboot on newly compiled kernel Actual Results: Kernel fails to boot, crashing early in the boot process. Expected Results: Kernel boots normally. Switching to the XZ compression method (CONFIG_KERNEL_XZ), or changing the USE flags for app-alternatives/bzip2[reference]
The last part should read: "Switching to the XZ compression method (CONFIG_KERNEL_XZ), or changing the USE flags for app-alternatives/bzip2[reference] both seem to work around this problem" I'm assuming the other compression methods may work as well, I just tried XZ first and it worked.
Assigning to the lbzip2 maintainer since I assume this is some bug in its compressor that makes it incompatible with the reference implementation. It could also be a kernel bug.
Can you attach your .config, please?

I've had a similar configuration fail now on 4 machines, 3 physical Core i7 boxes of various vintages and a KVM VM. After my system finishes updating today, I'll be running some further compiles to verify some assumptions. If there's any other data I can provide please let me know.
Your attached config has: # CONFIG_KERNEL_BZIP2 is not set Is this because you were testing and this is your config that works?
Yes, sorry that wasn't clear. I uploaded my current configuration, the previous one had: CONFIG_KERNEL_BZIP2=y and: # CONFIG_KERNEL_XZ is not set
Created attachment 849149 [details] Working bzip2 configuration with app-arch/bzip2 Performed another test. With the reference implementation of bzip2, and this kernel configuration I'm attaching, I was able to get 5.15.88 booted without issue. If I switch the bzip2 implementation to lbzip2, and recompile the kernel, the boot fails early. I have not yet tried pbzip2, but that may be my next test. I haven't yet compared the compressed data, or examined the kernel decompression routine to see if I can determine the cause.
Using pbzip2 as the default bzip2 also fails, although it may be even earlier in the boot process.
