Title: [18.04] GLK hang after a while Status in linux package in Ubuntu: In Progress Status in linux source package in Bionic: In Progress Bug description: SRU Justification Impact: i915 lacks information about the glk_dmc_ver1_04.bin firmware file in modinfo, so it is not included in the initrd along with the i915 driver. Thus the firmware does not get loaded. Loading the firmware is said to prevent a hang. Fix: Add a MODULE_FIRMWARE statement for the firmware. Test Case: Without the firmware there will be a "Direct firmware load for i915/glk_dmc_ver1_04.bin failed with error -2" line in dmesg. With the firmware there is no such message. Regression Potential: Minimal. Will only be loaded by i915 for specific hardware, and loading the firmware is known to fix a hang. --- Description: Platform information: Label: GLK02SDP Processor: Silver N5000 Bios: GELKRVPA.X64.0083.B30.1801162142 OS: Ubuntu 18.04 Kernel: 4.15.0-10-generic Details: Power on, and enter into the system; After a period, sometimes about 20 minutes, sometimes 1 hour, the machine will hang.
