But that was always the case, no? Yes, it would be nice to print real root device name in /proc/mounts, but it was "broken" for as far as I can remember...

After loads of testing I found out what is the problem: initramfs. I normally compile my own kernel with all the drivers built-in, and no initramfs ... and in this case, without initrd, it seems that / is somehow not remounted to a proper scsi device, but remains at /dev/root.

/dev/root changes with 3.17-rc
Hi everyone, (please cc) I am not sure whether this is a kernel bug, but: - booting with 3.16 I get / mounted on /dev/sda6 - booting with 3.17-rc* I get / mounted on /dev/root The later case disturbs grub (cannot find root device) as there is no /dev/root. I normally to make oldconfig when compiling a new kernel, all of the above are self-compiled.
