Subject: [Bug 199633] Stable kernel regression after 4.16.3: startxfce4 no longer works: X startup seems to hang

Message-ID: <bug-199633-2300-5GvDjJp2aK@https.bugzilla.kernel.org/> (raw)

--- Comment #4 from Klaus Kusche (klaus.kusche@computerix.info) ---
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.
