Description Gene 2017-01-03 02:14:40 UTC
have one laptop on which Kernels from 4.9-rc1 through 4.9 and 4.10-rc2 all fail to boot. 

        4.8.15 and all previous kernels have worked fine. 4.9-rc1 is first kernel which will not bo

        Refind prints the kernel boot command and then nothing happens at all. No output.
        I am booting using refind on a lenovo W540 laptop:

        Files attached: 
                + ver_linux.out = output of ver_linux
                + cpuinfo.out   = /proc/cpuinfo
                + lspci.out     = lspci -vvv
                + modules.out   = /proc/modules
                + scsi.out      = /proc/scsi/scsi 

        These machines all boot 4.9 no problem:

Is it worth adding a boot parameter to the kernel line during boot to get early printk by adding: "earlyprintk=efi,keep" and then posting the result even if taking a photo of the screen if the system has hung at that point?

Can you try and bisect it?

This is indeed a duplicate of 

Furthermore as in that bug this patch fixes the problem:


I applied this and tested 4.10-rc3 and with the patch it boots fine - Without it it does not. I have not yet tried patching 4.9.2 but I am pretty confident it will boot with the efi patch as well.
