Khurshid Alam, the next step is to fully reverse commit bisect from kernel 3.18 to 3.18.5 in order to identify the last bad commit, followed immediately by the first good one. Once this commit has been identified, then it may be reviewed as a candidate for backporting into your release. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F ?
Please note, finding adjacent kernel versions is not fully commit bisecting. Thank you for your understanding.

This happens for any compiz based session like gnome-flashback(compiz). I tried booting with both the systemd & upstart from boot menu, but the outcome did not change. Ctrl+Alt+F1 or Alt+SysRq does not work after freeze. Just before the freeze syslog prints following error: ---------------------------------------------------------------------- Jan 24 20:50:26 Compaq-610 kernel: [ 114.028185] WARNING: CPU: 1 PID: 0 at /build/buildd/linux-3.18.0/drivers/gpu/drm/i915/intel_display.c:9916 intel_check_page_flip+0xa7/0xb0 [i915]() Jan 24 20:50:26 Compaq-610 kernel: [ 114.028189] Kicking stuck page flip: queued at 16782129, now 16782130 & Compaq-610 kernel: [ 588.815146] gnome-system-lo[2937]: segfault at 14 ip b6c1f4c3 sp bff19e70 error 4 in libglib-2.0.so.0.4303. ----------------------------------------------------------------------- I have attached the complete syslog.txt & xorg.txt (http://paste.ubuntu.com/9852608/) for the session.
