Still need to pull the patch at 4.18.11 Do you mind posting a full dmesg log for your 4.18 kernel? It would probably help to have drm.debug=4 in your boot parameters as well for this. Created attachment 141963 [details]
dmesg output as requested
Added dmesg output as requested
commit 691f2d763d0731224439686ecf2d440df8fe910e is on branch linux-4.18.y of git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git. It was merged into branch master as part of commit 54dbe75bbf1e189982516de179147208e90b5e45 (In reply to Nicholas Kazlauskas from comment #2) > Do you mind posting a full dmesg log for your 4.18 kernel?

Created attachment 142387 [details] [review] Current work-around patch I am currently running Linux 4.19.1 with Attachment 142387 [details] and not seeing the problem. Might it be possible to instead use an approach like Attachment 142350 [details] to Bug 108139 to conditionally obey this code instead of removing it? I am currently running Linux 4.19.1 with Attachment 142387 [details] and not seeing the problem. Might it be possible to instead use an approach like Attachment 142350 [details] to Bug 108577 to conditionally obey this code instead of removing it? Since Linux 5.1, I do not see this bug any more. So I guess it is "fixed". |
