[ 545.764159] ACPI: Waking up from system sleep state S4 [ 575.844179] ACPI: \_SB_.PCI0.SATA.PRT1 - docking [ 575.849362] acpi LNXIOBAY:02: parent device:15 should not be sleeping at least this can give us some clues. It seems that there is an dock hotplug event before devices are resumed. please verify if boot option "acpi_sleep=old_ordering" helps. Hello, I tried with "acpi_sleep=old_ordering" but it doesn't help. Regards please attach the dmesg output after hibernate. Created attachment 25342 [details]
dmesg with acpi_sleep=old_ordering
Contrary to the logs above, this dmesg output does not show the 30 second delay - however, it still locks up for 30 seconds.
It's great that kernel bugzilla is back. can you please verify if the problem still exists in the latest upstream kernel? bug closed as there is no response from the bug reporter. please feel free to reopen it if the problem still exists in the latest upstream kernel. |
