To avoid the possibility that the issue is caused by corrupted binary, I've
recompiled a different version of Linux kernel, 5.15.95, and ran tests against
it as well:


$ llvm-addr2line -fie vmlinux 0xffffffff81c00290
__SCT__x86_pmu_handle_irq
??:0



$ eu-addr2line -fie vmlinux 0xffffffff81c00290
__SCT__x86_pmu_handle_irq
??:0



$ addr2line -v

This is the output from addr2line version with a Nick's patch:
