>Description:
I can not boot installed on the usb hdd (da0) system. An attempt to mount the root system is to define the system usb hdd:
Manual root filesystem specification:
<fstype>:<device> Mount <device> using filesystem <fstype>
eg. ufs:/dev/da0s1a
eg. cd9660:/dev/acd0
This is equivalent to: mount -t cd9660 /dev/acd0 /
? List valid disk boot devices
<empty line> Abort manual input
>How-To-Repeat:
>Fix:
edit /usr/src/sys/kern/vfs_mount.c
in 1655 line:
....
options = NULL;
+ pause("usbwait", hz * 10);
root_mount_prepare();
Add a pause of 10 seconds to mount the root filesystem during this time usb hdd will have time to define the system. Then recompile the kernel.
