Description Michal Jakubowski 2020-08-27 12:05:33 UTC 
Hello on genkernel-4.1.1 I cannot boot Gentoo on version 4.1.0-r2 works fine.
During boot I have error:
mounting /dev/sda1 on /newroot failed: No such file or directory

Reproducible: Always

I've assigned this but really some more information will be needed. emerge --info, the genkernel log, probably the logs from boot / screenshots.
Comment 2 Thomas Deutschmann (RETIRED) gentoo-dev 2020-08-27 15:17:39 UTC 
Please set

  gk.hw.use-modules_load=yes

on kernel command-line and see if this will make a difference.

If it does, please share kernel config and system details.
Comment 3 Thomas Deutschmann (RETIRED) gentoo-dev 2020-08-28 11:19:28 UTC 
And please share kernel command-line, used root fs and kernel config.

    defaults/linuxrc: Try to determine filesystem type
    
    'mount -t auto' will not trigger module loading for filesystem kernel modules.
    Therefore we try to determine filesystem to trigger module loading in case
    filesystem isn't built into the kernel.

Should be fixed in >=genkernel-4.1.2! Would be nice if you could test and report back!
Comment 6 Michal Jakubowski 2020-08-31 10:34:24 UTC 
On 4.1.2 is OK.

Thank you.
