Manjaro live: slow boot, dmesg: Warning! ehci_hcd should always be loaded before uhci_hcd and ohci_hcd, not after
Manjaro live boots extremely slow from usb2 flash on usb2 hardware. Quote from dmesg:
Warning! ehci_hcd should always be loaded before uhci_hcd and ohci_hcd, not after
It probably runs in usb1 mode, hence extremely slow. On usb3 hardware same usb2 flash boots several times faster, because it's using xhci_hcd instead.
This can be fixed for example with
/etc/modprobe.d/my.conf
softdep ohci_hcd pre:ehci_hcd
softdep uhci_hcd pre:ehci_hcd
