This error appeared for the first time today, it also seems to slow down the system, or at least network speed. Also getting the following new errors in dmesg:
[10678.935979] ACPI: BIOS _OSI(Linux) query ignored
[10806.726460] ath9k: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x00000020
[11676.858774] ath9k: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x00000020
No updates installed today. I'll try to reboot and check if the message reappears.
