Try switching to clang. Some time ago I was hit by different error - 
some process hangs indefinitely and can't be killed. After building 
system with clang I obtained a core dump at first reboot and research 
turned out that there was some broken directory entry in file system. 
Recreating damaged zfs filesystem (leaving all other pool intact) solved 
my problem completely.
