Date: Sat, 6 Sep 2008 17:29:53 -0700 From: Steven Noonan <steven.noonan@...inklabs.net> To: linux-kernel@...r.kernel.org Cc: Steven Noonan <steven@...inklabs.net> Subject: [PATCH 1/1] drivers/usb/host/pci-quirks.c: wait for EHCI handoff far too long in quirk_usb_disable_ehci() This patch fixes a very noticeable bootup delay on some systems (in my particular case, an HP dv5178us). The problem is caused by a buggy BIOS which doesn't properly announce that the handoff was completed. The delay in the current version of pci-quirks.c is 5 seconds, which I've cut down to 0.5 seconds.
