Created attachment 110224 [details] git bisect run 1 Machine freezes a few seconds after login I run the bisection twice as the results are strange. First bisection pointed to [a12624959ad4e3bfa8c344ad71728ffc9a379158] which is strange (I might have messed something up) Second run points to the merge commit [40d201af0b9e6196a210b97d3b2493b1156564f6] which is strange too. I have captured too traces from "good", as in not frozen, bisection points attached below. Machine: Toshiba Portege M700 Distro: Ubuntu 14.04 x86_64

can you ssh in from another machine? boot with nomodeset, then modprobe i915 modeset=1 and see it hangs or at least some stuff might get to logs. Looks like an i965GM.
I managed to ssh in the machine before the freeze but the connection does not survive the freeze. The same trace is there too. I also set-up a small script taking dmesgs at the default 2sec interval but this too dies after the freeze. I got 3 blank files and then it stopped trying alltogether. Booting with nomodeset is fine. Even after "modprobe i915 modeset=1" the machine lives on happily
This time, something like a minute after the hang and as I was trying to resurrect the ssh connection, the machine showed signs of life. I have a few screenlets running on the desktop among which a digital clock and two cpu graph indicators. The seconds started ticking and the cpu graphs started moving. No mouse or keyboard reaction but cpu1 graph was behaving normally showing fluctuations. cpu2 graph was moving but with at zero usage flat. Maybe it's just a side effect.

I did a third bisection focusing on the trace and starting with the merge as bad commit this time. The trace begins after commit d6bbafa183793537d8dca4d4c2e448805e59448a so I am cc'ing Chris.
