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...) -- Stefan Richter -==- -=-- ===-= http://arcgraph.de/sr/

Regression of v4.6-rc vs. v4.5: hangs after a few minutes after boot
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. -- Stefan Richter -==- -=-- ==-=- http://arcgraph.de/sr/
