After upgrading to Linux 3.7 (on Arch Linux, x86_64), I've been getting the following messages in dmesg:
[Dec11 21:52] hda-intel: azx_get_response timeout, switching to polling mode: last cmd=0x001f0500 [ +1.006709] hda-intel: No response from codec, disabling MSI: last cmd=0x001f0500 [ +1.006773] hda_intel: azx_get_response timeout, switching to single_cmd mode: last cmd=0x001f0500
This seems to happen when resuming from suspend-to-memory, and is new to v3.7 – I haven't seen any such messages on any kernels I've used earlier (between v3.0 and v3.6.9).
The device is:
# lspci -v 00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 06) Subsystem: ASUSTeK Computer Inc. Device 1643 Flags: bus master, fast devsel, latency 0, IRQ 22 Memory at d5200000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Capabilities: [60] MSI: Enable- Count=1/1 Maskable- 64bit+ Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00 Capabilities: [100] Virtual Channel Capabilities: [130] Root Complex Link Kernel driver in use: snd_hda_intel
Is there anything I can/should do about this?
