acpi crashing endlessly on shutdown

[Andrea G. Monaco]

Hello,


when I shutdown my system, I get this error

  /hurd/crash: /hurd/acpi(...) crashed, signal {no:11, code:1, error:1},
  exception {1, code:1, subcode:487424}, PCs:{0x1160c23, 0x10c029c},
  writing core file.

printed repeatedly forever, with a positive number inside the first
round parenthesis increased by one each time.
This happens roughly at the end of the shutdown process and hangs it.


Is this known or obvious?



Warmly, 
Andrea Monaco
