"[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun" on boot
Last modified: 2016-07-19 14:32:54 EDT
Description of problem ====================== Booting my olde laptoppe (a Fujitsu-Siemens Amilo Xi 3650) running: 4.2.6-200.fc22.x86_64 KDE the following can be found in the kernel log after the network has come up: Adjusting hpet more than 11% (2074996363 vs 2601267907) [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe B FIFO underrun Sometimes it is just "pipe A FIFO" which underruns. Is this a problem? Maybe: I noticed that the KDE boot screen (the one with the cogwheel shown before the login prompt appears) takes a LONG time to finish after this message appears. Today the boot didn't finish at all and I had to reboot from the text console. But maybe it's just the hardware getting flaky. Version-Release number of selected component (if applicable): ------------------------------------------------------------- 4.2.6-200.fc22.x86_64 KDE 01:00.0 VGA compatible controller: NVIDIA Corporation G96M [GeForce 9600M GT] (rev a1) How reproducible: ----------------- Every boot. Since September when I installed Fedora 22.
