Hi, It happened again with another machine, a R420, also running 5.4-stable. I can reproduce the problem giving a sequence of bioctl mfi0 commands:
(Please, do not try this on production servers) # for foo in `jot 1000`; do bioctl mfi0; sleep 1; done The kernel panics with: uvm_fault(0xffffffff81c96be0, 0xffff8000003e2000, 0, 2) -> e fatal page fault in supervisor mode trap type 6 code 2 rip ffffffff8136f566 cs 8 rflags 10206 cr2 ffff8000003e2000 cpl 0 rsp ffff8000221d8a38 panic: trap type 6, code=2, pc=ffffffff8136f566 Starting stack trace... panic() at panic+0xf5 trap() at trap+0x7f1 --- trap (number 6) --- memmove() at memmove+0x16 mfi_mgmt() at mfi_mgmt+0x6a mfi_bio_getitall() at mfi_bio_getitall+0x22e mfi_ioctl_vol() at mfi_ioctl_vol+0x1f mfi_refresh_sensors() at mfi_refresh_sensors+0xbf sensor_task_work() at sensor_task_work+0x21 workq_thread() at workq_thread+0x33 end trace frame: 0x0, count: 248 End of stack trace. ps output: USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND root 1 0.0 0.0 512 0 ??
