I have a mac book pro 2014 with MacOs 11.2.3
The kernel panics are driving me crazy and impacting my work seriously.
The usual pattern is the mac freezing followed by the question mark folder. It happens often after awaking, but also while is on since a while. The most common error is "Could not recover SATA HDD after 5 attempts. Terminating" but they are quite varied.
Also the frequency is quite random: sometimes is fine for days, sometimes it's every hour, with no discernible pattern in my usage.
I sent it to service to an authorized seller (unfortunately no apple stores nearby) and they said they found no hardware problems, only a lot of dust inside and a worn-out thermal paste. I run all possible apple tests and solution and just once the diagnostic tool showed a disk related problem, then never again.
I started to collect the panic log, maybe one of you will notice something recurring.
UPDATE I had an intuition and stopped using the airpods for one week. In that period no kernel panics occurred. As soon I started using them again the panics restarted (albeit at a lower frequency). So I'm starting to have compelling evidence it's them or the Bluetooth.
Apple does not seem to acknowledge the problem and insist about the SSD failing...
