Yeah, forcefully enabling semaphores on Tonga will crash rather fast. The purpose of vm_debug != 0 is to stop after the first VM fault. So if you got a VM fault from time to time which was just ignored than setting vm_debug will certainly crash the system. On the other hand you shouldn't get VM faults in the first place.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
