[Slackware64 14.2] Loading error of ath10k firmware with latest kernel-firmware and latest kernel-huge
Howdy :-)
I only installed the official package set and before I applied the system update, the ath10k firmware was successfully loaded. Then I updated the system with slackpkg upgrade-all. After that I rebooted the system and the ath10k firmware failed to load. The same happened with the reinstallation of latest kernel-firmware. Finally I downgraded kernel-firmware to the previous one installed and when I again rebooted the system, the ath10k firmware was successfully loaded with the latest kernel-huge. Is this a bug of ath10k firmware in latest kernel-firmware package? Thanks in advance! |
I applied the updates on my netbook and the firmware continues to load (I boot to a custom 4.17 kernel but that is irrelevant here):
Code:
[ 8.642391] ath10k_pci 0000:02:00.0: Direct firmware load for ath10k/pre-cal-pci-0000:02:00.0.bin failed with error -2 https://github.com/kvalo/ath10k-firmware |
Ilgar,
After reading /var/log/syslog, I noticed that Code:
ath10k_pci 0000:03:00.0: Direct firmware load for ath10k/cal-pci-0000:03:00.0.bin failed with error -2 I also noticed that the following output appears before but not after kernel-firmware downgrade: Code:
ath10k_pci 0000:03:00.0: firmware crashed! (uuid 761def23-1d0f-4661-8751-35a0c8cf7610) Thanks in advance! |
Yes I think the driver tries to load the firmware blobs present one by one until it finds the right one. That may explain the failed attempts which also appear in my log. But in you case the new firmware seems to be crashing. I can't tell which chip you have from the logs you provided, but I recommend that 1) you try to grab an older version of the blob, either from the git repo or by extracting it from the previous Slackware package, 2) once you verify that the old one works, report the issue to kvalo (AFAIK it is his git repo where the official development takes place).
As long as your devices work correctly, there is no harm in using an older version of the firmware package. But your bug report might be useful to other people, so you might consider digging this a little further. Good luck! |
