Description of problem: I generally get this right after rebooting. KDE finishes to load and then I see this crash report. Not sure if I`ve already reported this. Also note that I am having problems resuming from stand-by. The computer resumes, I see the log-in screen but 3 seconds later (no matter if I try to log in or not) everything freezes, only the mouse is still movable. I can not switch to a terminal log-in (ctrl-alt-f1/f2) nor can I restart X (ctrl-alt-backspace). This is the backtrace that I see in dmesg: [ 106.380332] WARNING: CPU: 4 PID: 691 at drivers/gpu/drm/i915/intel_dp.c:137 intel_dp_max_link_bw.isra.7+0x3e/0xa0 [i915]() [ 106.380334] invalid max DP link bw val 0, using 1.62Gbps [ 106.380335] Modules linked in: ipt_MASQUERADE iptable_nat nf_nat_ipv4 nf_nat nf_conntrack_ipv4 nf_defrag_ipv4 xt_conntrack nf_conntrack xt_CHECKSUM iptable_mangle tun bridge stp llc ip6table_filter ip6_tables ebtable_nat ebtables ccm arc4 iwldvm mac80211 uvcvideo videobuf2_vmalloc videobuf2_memops videobuf2_core snd_hda_codec_hdmi v4l2_common iwlwifi x86_pkg_temp_thermal snd_hda_codec_realtek videodev snd_hda_codec_generic media r8169 mii snd_hda_intel snd_hda_controller cfg80211 iTCO_wdt iTCO_vendor_support coretemp snd_hda_codec snd_hwdep snd_seq kvm_intel lpc_ich mei_me mei mfd_core dell_laptop dcdbas snd_seq_device rfkill shpchp snd_pcm kvm i2c_i801 dell_wmi sparse_keymap crct10dif_pclmul crc32_pclmul crc32c_intel ghash_clmulni_intel snd_timer snd soundcore serio_raw dell_smo8800 microcode nfsd [ 106.380366] auth_rpcgss nfs_acl lockd sunrpc binfmt_misc i915 i2c_algo_bit drm_kms_helper drm i2c_core wmi video [ 106.380373] CPU: 4 PID: 691 Comm: X Not tainted 3.16.2-201.fc20.x86_64 #1 [ 106.380375] Hardware name: Dell Inc.
