Extrapolated from the declarations of <reservation.h> and <ww_mutex.h> that the intention was (please correct if I'm wrong): if (reservation_object_lock(resv, NULL) == 0) { /* lock successfully acquired */ ... } Tested that, hard freeze persists. Re #14: Not sure, just pulled it out of the closet again. Played it years ago, but the kernels I ran back then didn't have IOMMU compiled in, if I remember correctly. I'll happily bisect this - what would be a good guess for how far to go back?</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 assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
