Is there a way (loader tunable or kernel config) to disable the root mount waiting for USB buses and devices and make it behave just like in the first days of the new USB stack ?
Why can't we just wait until the device node that should be mounted is available?
We're talking about this USB delay which appears almost always during the initialization of the USB stack.
Jul 19 07:21:34 ameagari kernel: Root mount waiting for: usbus7 usbus3 Jul 19 07:21:34 ameagari kernel: Trying to mount root from ufs:/dev/ad10s1a
In this case, the delay is insignificant, however with some systems this can take up to 10 seconds. And we don't even need to wait for USB bus because the root filesystem is on an ATA hard disk.
So that's why I'm saying: why can't we just wait until the device node that should be mounted is available?
Talk to Scott Long how to correctly fix this issue. Andrew Thompson tried but his attempt was backed out as incorrect. So far as I know noone has stepped up to address the real problem here.
