I have reported this on *several* occations over the last year or so, as have others. However, apart from some time early this year/late last year, it doesn't seem to have received due attention. This is a serious problem for anyone using 5.3 on a desktop - which I have very much legitimate reasons for doing - though I haven't really noticed problems on servers due to this. It seems to be linked to the system CPU load (not user CPU load), which would be logical. Everyone seemed to think it was ULE related (and this showed up long before PREEMPTION became an issue), but it is not... Here's to hoping someone looks into it - I certainly ain't capable of doing so ;) /Eirik PS: Apart from that I have to agree with what others have stated: 5.3 is a truly wonderful release... > And I never had this issue before with 4.x serie. > > I tried to boot with an without ACPI, with GENERIC kernel, with my "own" > kernel configuration (GENERIC with removed unused SCSI/RAID/NIC drivers) > both with and without PREEMPTION[1].
