| |
After reboot with kernel & firmware updates I found `failed to copy target iram contents:` in dmesg and missing wlan interfaces for both of my QCA9984 compex cards. Rolling back kernel/firmware didn't fixed it, so while I have no idea what's actually happening, I don't see why we should fail in this case, looks like some optional firmware ability that could be skipped.
Also with additional logging there is ``` [ 6.839858] ath10k_pci 0000:04:00.0: No hardware memory [ 6.841205] ath10k_pci 0000:04:00.0: failed to copy target iram contents: -12 [ 6.873578] ath10k_pci 0000:07:00.0: No hardware memory [ 6.875052] ath10k_pci 0000:07:00.0: failed to copy target iram contents: -12 ``` so exact branch could be seen.
