I've decided to try my hand at solving https://bugzilla.kernel.org/show_bug.cgi?id=195035, as it seems to only affect me, or at least people have been quiet about it. I've debugged the issue a bit and it is basically a SIGSEGV type of event. In efi_clean_memmap efi.memmap.map returns pointer to address 0xfffffffffff200000, which is obviously wrong, after which any attempts to validate in efi_memmap_entry_valid cause a panic, because of bogus pointer. Git bisects won't help much, because the issue was always present apparently, it just wasn't fatal (as seen in dmesg attached to the bug). I am kinda new to kernel programming in general, so I am seeking advice for debugging this.
