Thanks. Sorry for the delay, too many bugs to track... Has a bug on bugzilla.kernel.org been written or a patch been made for this issue? It seems to happen every 1.5 months. Last time it was seen was 1.5 months ago, so I guess we'll soon see if progress has been made!</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
