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. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
