ATA SCSI trace failing randomly

After the previous issue of AX210 bluetooth issues after warm reboots I got
another problem; after the system sleep and get woken up from it, the bluetooth
adapter stop completely to respond to the host, other times it will connect to
my bluetooth mouse for a few seconds and then the bluetooth subsystem locks up
randomly. Sometimes when it works and then stop working I see this message in
the dmesg log:

To fix this problem I usually put the laptop to sleep and wake it up again
Today however I was greeted with this error multiple times:

see ata_scsi_trace.txt

This laptop doesn't have a SATA port, but I guess the error comes from the
probing of the chipset non connected port? Why it crashes though?

Then this error is printed:

[10151.146976] ata2: failed stop FIS RX (-16)
[10151.148212] ata1: failed stop FIS RX (-16)

And then multiple new errors coming from a function called list (but it seems
that the caller is the bluetooth subsystem):

see list_stack_trace.txt

Then the bluetooth subsystem 4 times:

see bluetooth_stack_trace.txt

Finally after a sleep wake cycle again this was printed again:

see double_stack_trace.txt.

In this last case, however, the bluetooth works perfectly fine, after 3 cycles.

I don't really get what's happening here, frankly.

If you need more information on this, just ask.

Marco.
