BR, -Risto to 6. toukok. 2021 klo 7.57 Risto Paavola (risto.paav...@gmail.com<mailto:risto.paav...@gmail.com>) kirjoitti: Hello! I noticed that when I compiled 5.12 and 5.12.1 kernels my display started to flicker maybe in once a second. With kernel 5.11.16 or below that there is no flickering. I'm using Gentoo testing and all other packages remained the same when I switched between 5.11.16 and 5.12.X. I have attached a couple of videos to this email to demonstrate the problem with kernel version 5.12.1. Sorry about the file sizes. These are the errors I am seeing in journal: May 06 07:49:24 nyrkki kernel: ACPI Error: Needed type [Reference], found [Integer] 0000000090bcaee8 (20210105/exresop-66) May 06 07:49:24 nyrkki kernel: ACPI Error: AE_AML_OPERAND_TYPE, While resolving operands for [OpcodeName unavailable] (20210105/dswexec-431) May 06 07:49:24 nyrkki kernel: ACPI Error: Aborting method \_PR.CPU0._PDC due to previous error (AE_AML_OPERAND_TYPE) (20210105/psparse-529) May 06 07:49:47 nyrkki kernel: DMAR: DRHD: handling fault status reg 2 May 06 07:49:47 nyrkki kernel: DMAR: [DMA Write] Request device [00:02.0] PASID ffffffff fault addr c7fe5000 [fault reason 05] PTE Write access is not set May 06 07:49:47 nyrkki kernel: Bluetooth: hci0: unexpected event for opcode 0xfc2f May 06 07:49:49 nyrkki sddm-helper[2258]: gkr-pam: unable to locate daemon control file May 06 07:49:52 nyrkki kwin_x11[2322]: kwin_xkbcommon: XKB: couldn't find a Compose file for locale "en_FI.UTF-8" May 06 07:49:58 nyrkki systemd-coredump[4290]: [🡕] Process 2376 (baloo_file) of user 1000 dumped core. I have noticed that people were having these kinds of issues a couple of years ago with pstates and/or psr. Maybe this bug in the latest kernel is also related to them?
