I bisected the regression and found the first bad commit to be: 2ed8d2b3a81bdbb0418301628ccdb008ac9f40b7 "PM: Rework handling of interrupts during suspend-resume"
To those of you I cc'ed: sorry for the noise, but you were the ones that get_maintainers.pl spit out when asking for *adb*-files.
In addition to the diff of the lshal output I posted before, here is the diff in the output of lsadb:
