Can't boot kernel 6.17.4+ via rEFInd

[Eugene Shalygin]

Hi All,

I've got a problem booting the stable kernel 6.17.4 and 6.17.5 after
updating from 6.17.3 via make oldconfig. Out of my 4 amd64 machines
running Gentoo, two are unable to boot with rEFInd showing "Error: Not
Found while loading <kernel file name>." Bisecting kernel sources
points to commit 5b5cdb1fe434e8adc97d5037e6d05dd386c4c4c6.

All four machines use very similar toolchains: GCC 15.2.0 and
15.2.1_p20251018, binutils 2.45.

https://bugzilla.kernel.org/show_bug.cgi?id=220700 has kernel config attached.

Would appreciate any hints or suggestions.

Best regards,
Eugene
