Comment 126 for bug 1575467

Perhaps it is helpful to report my experiences to this topic. My Hardware: Acer Travelmate B115 with Pentium N3540, Kingston SSD SV300S37A240G.
One month ago I updated the system from 14.04 to 16.04. I got two problems. The first was a non working Broadcom WLAN. But this was the simple solution: The STA driver failed to load, if secure boot was activated in bios. The second problem was this terrible freezing after short uptime. I found only the solution with the kernel parameter „intel_idle.max_cstate=1". This option worked, but the battery lifetime decreased appreciably. Now I read the last entries in this thread, so I decided to make some experiments. I updated the firmware of the SSD drive with the tool from Kingston by using Windows. Unfortunately I didn't note the old version of the firmware. Afterward I removed the cstate boot option. I also not forgot to call update_grub. But - since I‘ve done this, I saw no freeze anymore.
