Kernel panic using logelevel or quiet
I am using an embedded device with onboard storage (mmcblk0).
The system is using UEFI (and GRUB), on mmcblk0 I have a GPT partition with 3 partition: root, configurations, swap.
My command to boot is:
linux /vmlinuz root=/dev/mmcblk0p1 net.ifnames=0 splash
Now my problem is that when I set the quiet or loglevel param, it fails to boot and hangs up in a kernel panic. When I don't set one of those it boots perfectly. Root param is always the same.

How do you set quiet? Like thislinux /vmlinuz root=/dev/mmcblk0p1 net.ifnames=0 quiet splash?

@mmmint correct. Either before or after splash, Loglevel can be 0-7, no matter which level i set, all end in a kernel crash.

It seems root FS is not ready when you kernel tries to load it. Use rootwait or rootdelay in your kernel command line should solve the issue.

Why do you suppose this would be correlated with thequiet/loglevelsetting? Please do not respond in comments; edit your answer to make it clearer and more complete.
