Date: Thu, 4 Oct 2012 14:15:27 -0700 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, alan@...rguk.ukuu.org.uk, Alan Stern <stern@...land.harvard.edu> Subject: [ 06/56] USB: EHCI: convert warning messages to debug-level 3.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Alan Stern <stern@...land.harvard.edu> commit d16ba48774913d244c7eb894d28d8ae2c019a827 upstream. This patch (as1606) converts two warning messages in the ehci-hcd driver to debug messages, and adds a little extra information to each. The log messages occur when an EHCI controller takes too long (more than 20 ms) to turn its async or periodic schedule on or off. If this happens at all, it's liable to happen quite often and there's no point spamming the system log with these warnings. Furthermore, there's nothing much we can do about it when the problem happens.
