Subject: drivers/base/firmware_class.c:1127  can't find firmware file

Hello,

at a hardened 64 bit Gentoo Linux (Lenove T440s) I played with s2disk/s2ram and observed then this in the syslog (the firmware is there, I happened just today 2x and at 15th of December -and I do s2mem few times  per day) :
