After it proved impossible to capture an oops through netconsole, I
started git bisect.  This will apparently take almost a week, as git
estimated 13 bisection steps and I will be allowing about 12 hours of
uptime as a sign for a good kernel.  (In my four or five tests of bad
kernels before I started bisection, they hung after 3 minutes...5.5 hours
uptime, with no discernible difference in workload.  Maybe 12 h cutoff is
even too short...)

One more hang, now after 12 minutes uptime.
Again no netconsole output.

For the time being I can't investigate further.

Today I booted a 2nd time into v4.6-rc5, and loaded netconsole shortly
after boot and xdm login to try capturing an oops.  But throughout 5 hours
uptime now, the hang was not reproduced.

Regression of v4.6-rc vs. v4.5: hangs after a few minutes after boot

2016-04-26 Thread Stefan Richter
Hi,

v4.6-rc solidly hangs after a short while after boot, login to X11, and
doing nothing much remarkable on the just brought up X desktop.

Hardware: x86-64, E3-1245 v3 (Haswell),
  mainboard Supermicro X10SAE,
  using integrated Intel graphics (HD P4600, i915 driver),
  C226 PCH's AHCI and USB 2/3, ASMedia ASM1062 AHCI,
  Intel LAN (i217, igb driver),
  several IEEE 1394 controllers, some of them behind
  PCIe bridges (IDT, PLX) or PCIe-to-PCI bridges (TI, Tundra)
  and one PCI-to-CardBus bridge (Ricoh)

kernel.org kernel, Gentoo Linux userland

1. known good:  v4.5-rc5 (gcc 4.9.3)
   known bad:   v4.6-rc2 (gcc 4.9.3), only tried one time

2. known good:  v4.5.2 (gcc 5.2.0)
   known bad:   v4.6-rc5 (gcc 5.2.0), only tried one time

I will send my linux-4.6-rc5/.config in a follow-up message.

In theory I could collect more info (simplify the hardware, run
netconsole, bisect).  In practice I cannot do so for the the time being
due to lack of spare time.  That's also the reason why I did not already
send a report when I tested v4.6-rc2, and why I did not boot v4.6-rc[25]
more than once yet.
