A bit of a nuisance, but could you bisect the hard lockup? Assuming it's not rogue hardware, hard lockups are usually broken locking (e.g. recursive irq-off spinlocks). Trying a build with lockdep enabled may help - at least to get a warning out.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
