Just to clarify: it's commit 9477c58e3308f54a108a5d1eb9621830b329b0ca that is bad.
It causes odd stuttering/echoing effects on my bog-standard Westmere setup:
00:00.0 Host bridge: Intel Corporation Core Processor DRAM Controller (rev 12) 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 12) 00:16.0 Communication controller: Intel Corporation 5 Series/3400 Series Chipset HECI Controller (rev 06) 00:1a.0 USB Controller: Intel Corporation 5 Series/3400 Series Chipset USB2 Enhanced Host Controller (rev 06) 00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 06) ...
with dmesg saying:
HDA Intel 0000:00:1b.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22 HDA Intel 0000:00:1b.0: irq 52 for MSI/MSI-X HDA Intel 0000:00:1b.0: setting latency timer to 64 hda_codec: ALC889: BIOS auto-probing. HDMI status: Pin=6 Presence_Detect=0 ELD_Valid=0 input: HDA Intel HDMI/DP as /devices/pci0000:00/0000:00:1b.0/sound/card0/input2 input: HDA Intel Headphone as /devices/pci0000:00/0000:00:1b.0/sound/card0/input3 ALSA device list: #0: HDA Intel at 0xfb9f4000 irq 52
and I'm not seeing anything odd with the bad kernel, but the long-on "boing" sound repeats about once a second as an echo and some corruption for a few seconds, and trying to listen to music or anything else is just psychedelic (more echo/stutter effects).
