Comment 223 for bug 1239578

I've been having lot of freezes with fedora 20/21 kernels 3.15, 3.16, 3.17 (maybe sooner). In my opinion it is related to bug I (and others) have reported https://bugzilla.redhat.com/show_bug.cgi?id=1149632 . Yesterday I reinstalled fedora back to 3.11.10-301.fc20.x86_64 and it looks like when I disable bluetooth in bios then it is going without freezes (but network-manager + nm-applet are connecting very bad to even non secured wifi connections). With enabled bluetooth I had BUG: soft lockp - CPU#0 stuck for 22s! - this message and some other info was written to terminal but keyboard/touchpoint/trackpad were not functional, had to do hard reboot. My system is thinkpad t540p with latest bios.
