Hi ming I did some tests on my local. [ 598.828578] nvme nvme0: I/O 51 QID 4 timeout, disable controller This should be a timeout on nvme_reset_dev->nvme_wait_freeze. [ 598.828743] nvme nvme0: EH 1: before shutdown [ 599.013586] nvme nvme0: EH 1: after shutdown [ 599.137197] nvme nvme0: EH 1: after recovery The EH 1 have mark the state to LIVE [ 599.137241] nvme nvme0: failed to mark controller state 1 So the EH 0 failed to mark state to LIVE The card was removed. This should not be expected by nested EH. [ 599.137322] nvme nvme0: Removing after probe failure status: 0 [ 599.326539] nvme nvme0: EH 0: after recovery [ 599.326760] nvme0n1: detected capacity change from 128035676160 to 0 [ 599.457208] nvme nvme0: failed to set APST feature (-19) nvme_reset_dev should identify whether it is nested. Thanks Jianchao
