Guys, I appreciate the work and effort being done in the i915 driver (I've spent a lot of time looking at the code thinking I could help fix this and it's highly complex) but it's been three weeks now and this regression is killing my workflow- so I "fixed" the issue by reverting Sept 19th's drm-next merge from Linus' master[1], and I've had reliable operation again for days now. I'll keep watching for the next DRM update, and I really hope this is happening in enough places to give you guys and idea of what's been happening so it can get fixed, but I can't beta-test this code any longer ... sorry. I still have the branch with the faulty DRM code and the next time I reboot I'll try to remember to add "drm.debug=0x1e" to the cmdline and boot the faulty branch, though so I can upload the dmesg. [1] - Turned out to be less painful than I'd thought, too- if anyone else needs to do this, it's "git revert -m 1 574cc4539762", checking out to "HEAD" of all the conflicted devices not i915, fixing up a minor conflict in .../i915/ and cherry-picking 72e67f0463</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
