Getting "system is deadlocked on memory" errors after rebooting after updating to the latest kernel and bootloader packages (using the pi 4 specific kernel).
Updated both of them at the same time, so unsure which of the two is the culprit. Will try to roll them both back later in the afternoon (it deadlocks after a minute or two, getting progressively more unresponsive, so I have to revert the updates immediately after reboot then sync and reboot again), but thought I'd let you know about this serious issue here
(Couldn't find any obvious bug tracker)
