waiting for root takes more than 10 seconds?

I am trying to boot from an usb-stick on an older AMD K7 machine.

On boot, I get something like this:

:: Triggering uevents...done.
Waiting 10 seconds for device 'LABEL=sat_usb_k'
ERROR: Unable to find root device 'LABEL=sat_usb_k'
You are being dropped to a recovery shell
       Type 'exit' to try and continue booting

Now I only type 'exit' to exit the recovery shell and the booting continues without further issues, meaning the root device "LABEL=sat_usb_k" is mounted.

It seems to me, that 10 seconds of waiting are just not enough. If I am right: Does anyone know how to change the waiting time? If not, any other suggestions?

Re: waiting for root takes more than 10 seconds?

I found the  kernel parameter

rootdelay

.
Adding, e.g.,

rootdelay=30

to my boot(kernel-)parameters seems to achieve exactly the behaviour I needed. Some further tests, and I'll consider this solved.

Strangely,

rootwait

had no effect so far on my machine, it still announces to wait 10 seconds for root device to appear and fails into emergency console as described above.

Nice it works. For rootwait see https://bbs.archlinux.org/viewtopic.php … 9#p1066469
