Hi,
We are experiencing failures with QCA9377 wifi, using Linux 4.18 and

followed by many more similar warnings.
This problem can be easily reproduced by playing youtube videos for a
few minutes. When it happens, the system does not recover and the wifi
is unusable til reboot.
We have confirmed that this problem only affects specific cards. Other
identical-looking QCA9377 cards found in other instances of the same
laptop products do not suffer the problem. If we move an affected card
to another laptop, the problem will then readily occur on that laptop
too, i.e. the problem follows the card.
Having seen multiple cards that follow this pattern, it does not
appear to be a one-off.
It also does not appear to be an actual defect with the hardware
because we've tested the same cards extensively under Windows 10 and
no problems are seen there.
Any suggestions for further debugging?
We would be happy to ship affected devices to Qualcomm engineers if that helps.
Thanks

Is this a regression? For example, have you tried older firmware
versions?

Sorry for the delayed response, as we were testing old versions.
It doesn't seem to be a regression, at least we tested:
