I have a T100HAN in my personal hw collection, so I just booted up a nightly build of the Fedora 32 workstation livecd on it and that works fine for me. This nightly build is using a 5.6 kernel.
So the 5.6 kernel can work on this hardware. AFAIK Ubuntu, like Fedora puts the i915 driver in the initrd. I guess either a module is missing from the initrd, or there is a module loading ordering issue going on here. The T100HAN uses a Crystal Cove PMIC. Here are the setting from a couple of relevant Kconfig options which Fedora uses: CONFIG_INTEL_SOC_PMIC=y CONFIG_PWM_CRC=y CONFIG_GPIO_CRYSTAL_COVE=y CONFIG_PMIC_OPREGION=y CONFIG_BYTCRC_PMIC_OPREGION=y CONFIG_CHTCRC_PMIC_OPREGION=y Note these are all builtin for Fedora, perhaps you can do a test build of an Ubuntu kernel with the same settings? Also can you attach, or email me the .config Ubuntu is using for building their kernels? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1860754 Title: ASUS T100HAN boots to a blank screen with a cursor [i965: Failed to submit batchbuffer: Input/output error] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1860754/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
