Peter Ujfalusi 3b2f36068c ASoC: SOF: Intel: hda-dsp: Make sure that no irq handler is pending before suspend ... [ Upstream commit 576a0b71b5 ] In the existing IPC support, the reply to each IPC message is handled in an IRQ thread. The assumption is that the IRQ thread is scheduled without significant delays. On an experimental (iow, buggy) kernel, the IRQ thread dealing with the reply to the last IPC message before powering-down the DSP can be delayed by several seconds. The IRQ thread will proceed with register accesses after the DSP is powered-down which results in a kernel crash. While the bug which causes the delay is not in the audio stack, we must handle such cases with defensive programming to avoid such crashes. Call synchronize_irq() before proceeding to power down the DSP to make sure that no irq thread is pending execution.
