https://bugzilla.kernel.org/show_bug.cgi?id=199633 --- Comment #4 from Klaus Kusche (klaus.kusche@xxxxxxxxxxxxxxx) --- Found time to bisect, the result was a surprise: The culprit is the random patchset by Theodore Tso: [1/5] random: fix crng_ready() test [2/5] random: use a different mixing algorithm for add_device_randomness() [3/5] random: set up the NUMA crng instances after the CRNG is fully initialized [4/5] random: crng_reseed() should lock the crng instance that it is modifying [5/5] random: add new ioctl RNDRESEEDCRNG Don't know exactly which one of those five, because the results with only part of the patchset applied are inconsistent. To double-check the result, I installed a 4.16.9. X session startup failed as described above. Then I replaced drivers/char/random.c in 4.16.9 with the 4.16.3 version and this fixed X startup. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
