Console doesn't response but ping and sshd sessions still work. procstat output is below. In addition, this doesn't happen to systems that I've been following 13-CURRENT but rather happen only wiht a system upgraded from 12.2-RELEASE to 13-RC. # procstat -kk 1049 PID TID COMM TDNAME KSTACK 1049 100215 kldload - spa_init+0xc6 zfs_kmod_init+0x1a zfs_modevent+0x34 module_register_init+0x8c linker_load_module+0xaab kern_kldload+0xc1 sys_kldload+0x50 syscall+0x17d g_ctx+0xe280bf29
