As the issue didn't reproduce the way I would have liked (did not reproduce at all here, not even with the same kernel version; no further comment) I have now uploaded the /proc/kcore and the kernel binaries and symbol files I still had on disk at https://upload.elstel.info (This may move to something like upload.elstel.info/bugs/kernpagealloc in the future) Regards, Elmar Am Fri, Jun 23, 2023 at 07:36:21PM +0700 schrieb Bagas Sanjaya: > Hi, > > I notice a regression report on Bugzilla [1].

On the third attempt something strange did happen. It seemed to write to disk as it should, the screen turned black but the power led and button still stayed alighted. Waking up by pressing the power button did not yield any effect, nor the SysRq keys (alas forgot to write 511 to >/proc/sys/kernel/sysrq). After a hard power reset it booted as if not hibernated. On the first hibernation attempt I could see lengthy and intermittent disk access.
