Package: firmware-atheros
Version: 20180518-1
Severity: important
Tags: upstream

Dear Maintainer,

I observed this while upgrading non-free firmware from stretch
(20161130-4) to stretch-backports (20180825+dfsg-1~bpo9+1) my QCA9377
quit working. Whether during boot or manually: When modprobing
ath10k_pci, the device either appears in my network stack, or it does
not, depending on the firmware version. In the latter case, that is
because its firmware instantly crashes, according to dmesg. I pinned
that down to: up to 20170823-1 works, 20180518-1 and after does not,
including 20190114-1. Looking at changelog.Debian, the break seems to
have been caused by this change:
"
firmware-nonfree (20180518-1) unstable; urgency=medium
 * New upstream version:
   - atheros:
     + QCA9377 rev 1.0 firmware version WLAN.TF.1.0-00002-QCATFSWPZ-5
"
According to dmesg, this "upgrade" replaced WLAN.TF.1.0-00267-1, which
was at least partially working for me. (only crashing occasionally as
described in #885846, and having trouble with big packet sizes, but
generally working) Comparing these QC firmware version numbers, they
look to me like the debian package upgrade actually included an upstream
downgrade. That of course would be the culprit, and a reason to rename
this bug report. You might want to check this hunch with upstream, and
with their versioning scheme. I suspect that #903437 might have the same
cause. And if there is a better QC-firmware than WLAN.TF.1.0-00267-1,
that might even resolve #885846 as well.

I'd love to see at least stretch-backports not breaking device
functionality. Please let me know about how else I may assist you in
that. FWIW, I'll attach the dmesg of when it's crashing, and my lspci
(-v and -vv) in (half-)working condition. My kernel is
linux-image-4.9.0-8-amd64_4.9.130-2 from stretch.

Best regards
Kevin Price
