ThinkPad Cannot Reboot After Hibernation
Last modified: 2020-07-30 09:42:39 UTC
I can reboot from a freshly booted system, but after hibernation I cannot reboot the system. The X250 will enter & resume hibernation just fine. But a reboot will hang with black screen after successfully shutting down & attempting to reboot. A minute or so will pass then the Fn key light will light up (as it does on a fresh boot) But computer hangs then gives up & shuts down. The hibernation icon will then be missing from Power/Session. Please let me know of relevant logs.
First off, is this a regression by the recent updates? The symptom sounds like some ACPI-related problem, and if you can reproduce reliably, the best would be to report this to upstream, e.g. bugzilla.kernel.org. Feel free to put me (tiwai@suse.de) to Cc there in case you need any assist from distro side.
Been going on for at least six months, never got round to reporting. It will also display same behaviour randomly on fresh boot but this cannot be reliably reproduced. I will report upstream & cc you as requested. Thx.
The kernel also spits out some errors before Plymouth, not sure if related.
OK, if it's an intermittent problem, it's hard to debug... Do you have some relevant kernel WARNING or Oops messages when the problem happens? If yes, it can be a good hint.
Nothing but a blank black screen at the time. But maybe permanent error before Plymouth mentions something, how would I retrieve boot log?
The bug is entirely reproducible on my hardware.
Lee, have you reported the issue upstream as mentioned previously? Could you provide a link, please? Also, does the issue persist with the current TW kernel?
Closing. No response.
