No it will; I don't check for EAGAIN specifically yet, but just a non-zero return. I want to make it check for specific error codes but want to see what actually is coming through when the patch's code gets hit. I agree that while the kernel guys say it should be EAGAIN, the data I've seen so far suggests a different error code (maybe EACCESS). > I also think this is probably an issue in plymouth because plymouth is > told to quit and release drm before X starts but it somehow does not > allways do this in time.

Well maybe, however we've seen people disable plymouth but still hit the race condition. My goal with this patch is to fix it on the X side so it'll work in the general case of anything holding the drm device too long. > You can try to change the X patch in #31 to spin also on EACCESS (bad > solution imho) or plymouth should be fixed to really release drm when > told to quit. > > And I also had this problem in Fedora, someone else reported it at > https://bugzilla.redhat.com/show_bug.cgi?id=855677 Thanks. > I reenabled plymouth-splash and will play a little with it again, but it > happens randomly in maybe 1/10 reboots so it's not easy to hit. Yeah, and it's possible there are several different failure modes depending on how the race is run, each needing a separate fix. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libdrm in Ubuntu. https://bugs.launchpad.net/bugs/982889 Title: X trying to start before plymouth has finished using the drm driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libdrm/+bug/982889/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
