dmesg 13

I have a F+ laptop, which has strange behavior regarding battery: when it's
being charged it charges to 100% and then battery light turns off and
uncharging begins even if I don't remove the AC, this uncharging continues
until 0% and laptop turns off, this behavior is not presented in -current -
everything works there as expected, i tried to bisect the commit, but it seems
we had a zfs update and when I try to find first bad commit kernel can't mount
root zfs FS with error 45, if I use UFS, laptop simply won't run more than 5
minutes and hangs with some error messages regarding nvme0 and being unable to
complete the i/o

acpidump -dt on 13 is interrupted with 'acpidump: DSDT is corrupt', on 14 this
command runs fine
