Fedora 23 randomly freezes on kernel 4.4

I have a Thinkpad 11e laptop that I installed Fedora 23 on with version 4.2 of the Linux kernel. A recent system update updated the kernel to 4.4. Since then I've had problems with the system randomly freezing, sometimes 20 minutes into a session, sometimes a couple of hours in. I see no pattern in what causes the system to hang; hibernation, video and audio playing or random use all seem to work normally until the system hangs. However, if I choose to boot the system with kernel 4.2, I have no problems.

Can anyone think what the problem could be, or what information I could give to help debug this? I added the output of uname -a, lspci -v and lsmod below in case that helps.

uname -a:

Linux cromwell.localdomain 4.2.3-300.fc23.x86_64 #1 SMP Mon Oct 5 15:42:54 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Until you get this problem fixed, I recommend to increase the number of kernels to keep on your system to at least 5. That way your working 4.2 kernel remains installed longer. (setting is in /etc/dnf/dnf.conf, entry installonly_limit=3). Most recent kernel for F23 is 4.5.5, see here(soon 4.5.6) Try another update(sudo dnf --refresh upgrade and see if that helps).

As for the problem, no clue what could cause it.

Do you see anything suspicious in dmesg -H or in journalctl | grep ERROR

I don't have the reputation to comment, but upgrading to kernel 4.5.5 seems to have fixed whatever the problem was. I've had no crashes for a few days now.
