Subject: [PATCH] EHCI pci-quirks.c: wait for BIOS handoff too long
Date: Mon,  3 Nov 2008 20:57:15 -0800	[thread overview]
Message-ID: <1225774635-15032-1-git-send-email-steven@uplinklabs.net> (raw)

Instead of waiting a painful 5000ms, quirk_usb_disable_ehci() now does a
1000ms loop to wait for the BIOS to acknowledge the handoff.
