I get same panic now (current of yesterday). panic: warning: pmap_changebit didn't. panic Stopped at Debugger+0x2c: ldq ra,0(sp) <0xfffffe000ce0bbe0> <ra=0xfffffc0000485800,sp=0xfffffe000ce0bbe0> db> trace Debugger() at Debugger+0x2c panic() at panic+0xfc pmap_emulate_reference() at pmap_emulate_reference+0x120 trap() at trap+0x2b0 XentMM() at XentMM+0x20 swapout_procs() at swapout_procs+0x174 (null)() at 0 I can generate crash dump, but it must be more than 500MB. I'll leave it in DDB for while.
