Yeah, sorry, not my best effort, but we were in the middle of a crisis. :) This is 8-stable (post 8.2-RELEASE) i386. > Can you reproduce it? If so, how? Not at will, but it's happened twice now. >> panic: 0xc63dd000 must be migratable >> cpuid = 1 >> panic: 0xc63dd000 must be migratable >> cpuid = 1 >> panic: 0xc63dd000 must be migratable >> cpuid = 1 >> panic: 0xc63dd000 must be migratable >> cpuid = 1 >> panic: 0xc63dd000 must be migratable >> cpuid = 1 >> panic: 0xc63dd000 must be migratable >> cpuid = 1 >> panic: 0xc63dd000 must be migratable >> cpuid = 1 This is the bit we see.
