Maybe it is similar to what Russell King reported. Probably not. The bug report above is with PCIe device. The dmesg attached to the bug report shows user is doing system suspend/resume over and over until the following occurs: [28151.874963] brcmfmac: brcmf_psm_watchdog_notify: PSM's watchdog has fired! [29354.351337] brcmfmac: brcmf_psm_watchdog_notify: PSM's watchdog has fired! PSM is the hardware block which processes the 802.11 packets received from firmware and passes them to the phy layer. When this watchdog barks the firmware will end up in a trap. We do collect a devcoredump upon the watchdog, but unfortunately that will not tell much about the failure in the hardware block. On monday I will try to come up with a patch to obtain more information from the device regarding this watchdog. Regards, Arend ^ permalink raw reply [flat|nested] 3+ messages in thread

I've also noticed problems with brcmfmac dropping out since 4.19, though haven't seen any notices about PSM: https://bugzilla.kernel.org/show_bug.cgi?id=201853. ^ permalink raw reply [flat|nested] 3+ messages in thread
