Hey guys, Just wanted to point you out to the bug report: https://bugzilla.kernel .org/show_bug.cgi?id=196819 --- Kernel 4.10.15-200.fc25 boots as expected, instead the following new kernels do not: - 4.11.12-200.fc25 - 4.12.8-200.fc25 - 4.12.8-300.fc26 How reproducible: If I try to boot the laptop nothing happens, it stays black. Instead with the kernel 4.10.15-200.fc25 the fedora logo appears and boots without any problems. If it matters the laptop has an intel celeron and after bisecting I've found that the culprit is the following commit: 282a4e4ce5f99e3c166abac929498885a711e19f is the first bad commit commit 282a4e4ce5f99e3c166abac929498885a711e19f Author: Irina Tirdea <irina.tirdea@xxxxxxxxx> Date: Mon Jan 23 12:07:44 2017 -0600 platform/x86: Enable Atom PMC platform clocks The BayTrail and CherryTrail platforms provide platform clocks through their Power Management Controller (PMC). The SoC supports up to 6 clocks (PMC_PLT_CLK[0..5]) with a frequency of either 19.2 MHz (PLL) or 25 MHz (XTAL) for BayTrail and a frequency of 19.2 MHz (XTAL) for CherryTrail. These clocks are available for general system use, where appropriate. For example, the usage for platform clocks suggested in the datasheet is the following: PLT_CLK[0..2] - Camera PLT_CLK[3] - Audio Codec PLT_CLK[4] - PLT_CLK[5] - COMMs Signed-off-by: Irina Tirdea <irina.tirdea@xxxxxxxxx> Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxx el.com> Acked-by: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx> Signed-off-by: Stephen Boyd <sboyd@xxxxxxxxxxxxxx> For reference here you have also the downstream bug report I've filed: https://bugzilla.redhat.com/show_bug.cgi?id=1486005
