The following error is seen on on entering suspend ... [ 58.222033] spi_master spi1: could not stop message queue [ 58.222038] spi_master spi1: queue stop failed [ 58.222048] dpm_run_callback(): platform_pm_suspend+0x0/0x54 returns -16 [ 58.222052] PM: Device 7000da00.spi failed to suspend: error -16 [ 58.222057] PM: Some devices failed to suspend, or early wake event detected Bisecting today's -next points to commit 412e60373245 ("spi: core: avoid waking pump thread from spi_sync instead run teardown delayed") and reverting this on top of -next fixes the problem. I have not had chance to dig any further but wanted to report this issue to see if you have any thoughts. Cheers Jon -- nvpublic
