IPEHR gives part of the pixel shader program and not the instruction itself -- suggests something went wrong with the parsing. Coherency? Cachelines? Fencing? The other possibility is the state setup throws off the parser, e.g. a tiled surface not aligned. It is only using 0x00900000 as the X tiled destination, and 0x07000000 as the Y tiled source (glyph atlas). So it looks fine, unless we've missed an 945g peculiarity (and tiling is indeed peculiar). @Vasily, Results from latest drmtip (https://cgit.freedesktop.org/drm-tip) would be helpful in this case. Can you please reproduce this issue with latest drmtip? Created attachment 144397 [details]

@jshand2013 According to log - I'm not sure that your problem is related to this bug: it refers to a much newer HW then gen3 (DP present in connectors) and the HANG is triggered after org_kde_powerdevil tries to do something with power-saving. Vasily, any results from drmtip testing? I didn't perform testing on more fresh than 5.1rc yet. I'll notify if I test more fresh kerenl. However it looks that it is harmless - I've seen it ~10 times (for the the last several months) now and it never even crashed the browser which uses HW acccel. The biggest seen visible problem is screen flicker. So I'm lowering importance level Several years ago similar problem made me mad due to completely hanging the system every 2-3 weeks. Now the situation is MUCH better. Thank you for still supporting gen3! -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
