Public bug reported:
Hi,
Updating my RPI4 this week SMB performances dropped from consistent
>=100MB/s to 60-70MB/s. Not much were updated recently, it may comes
from the kernel 5.13.0-1016-raspi (a guess). At this time I'm fully
updated but the last kernel 1017 seems not active yet (flash-kernel not
triggered) even if present on the /boot
Does it ring a bell?
