I have a 300-15IBR machine,It can enter OS with kernel3.19 in legacy mode, While in uefi mode, it can not enter OS successfully. But if I add the parameter nomodeset in grub, I can enter OS successfully in uefi mod,So i think maybe it is the problem of i915. By the way, I have tried kernel4.0 and kernel4.1, but I can not enter OS both in legacy mode and uefi mode. Does kernel3.19/kernel4.0/kernel4.1 support braswell now? Below is some info of my machine, if you need more info, please let me know: [root@localhost ~]# lspci -nn 00:00.0 Host bridge [0600]: Intel Corporation Device [8086:2280] (rev 21) 00:02.0 VGA compatible controller [0300]: Intel Corporation Device [8086:22b1] (rev 21) 00:13.0 SATA controller [0106]: Intel Corporation Device [8086:22a3] (rev 21) 00:14.0 USB controller [0c03]: Intel Corporation Device [8086:22b5] (rev 21) 00:1a.0 Encryption controller [1080]: Intel Corporation Device [8086:2298] (rev 21) 00:1b.0 Audio device [0403]: Intel Corporation Device [8086:2284] (rev 21) 00:1c.0 PCI bridge [0604]: Intel Corporation Device [8086:22c8] (rev 21) 00:1c.3 PCI bridge [0604]: Intel Corporation Device [8086:22ce] (rev 21) 00:1f.0 ISA bridge [0601]: Intel Corporation Device [8086:229c] (rev 21) 00:1f.3 SMBus [0c05]: Intel Corporation Device [8086:2292] (rev 21) 01:00.0 3D controller [0302]: NVIDIA Corporation Device [10de:1299] (rev a1) 02:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd.

The bsw support before v4.1 is preliminary, and you'll need the i915.preliminary_hw_support=1 parameter or CONFIG_DRM_I915_PRELIMINARY_HW_SUPPORT=y config option set. I don't think we'll spend much time debugging issues with that. Can you reproduce the problem with v4.1-rc3?

Yes, i can reproduce with v4.1-rc3, and it is worse than v3.19. With v4.1-rc3 I can not enter OS both in UEFI mode and Legacy mode. Even i add "nomodeset" and "init 3" parameter, the kernel can not boot successfully, it hangs in the UI as attachment.
Hi, Why can't i enter os even with kernel4.1-rc5 in my braswell machine? IS its graphic in the support list of kernel4.1? The graphic info is: VGA compatible controller [0300]: Intel Corporation Device [8086:22b1] If it is in the support list, why can't i boot? How can i debug? If it is not in the support list, when will it be supported?
Hi jani, Our OS still can not boot in this braswell with kernel4.1 graphics driver.According to dmesg as attachment, it seems i915 crashes. Could you help us take a look at the crash info in dmesg and xorg as attachment. And if you have any discovery, please tell us, our schedule is urgent, thanks.
