ehci_sync_hc timeout on loongson



Hi folks.

I've been trying to use a lemote yeeloong. it has internal usb wifi and
usb is on pci.

wifi occasionally works fine, and sometimes it will say 'ehci_sync_hc
timeout' and fail to work until I reboot.

I'm wondering what it could be, but don't know what to look for. some
low power mode for USB/PCI?

Any idea?
