Hi, it's the person speaking ;) It seems that I spoke too early. About an hour ago my box hung, but this time it didn't panicked (it isn't since ~Oct. 12). And as confirmed by Rory, it's seems that powerd isn't responsible. The only thing I was able to do has been switching to ttyv0 but after entering my login, it didn't prompted for the password. In the meanwhile, messages similar to the following were popping out: acd0: WARNING - PREVENT_ALLOW taskqueue timeout - completing request directly acd0: WARNING - PREVENT_ALLOW freeing taskqueue zombie request acd0: WARNING - TEST_UNIT_READY taskqueue timeout - completing request directly acd0: WARNING - TEST_UNIT_READY freeing taskqueue zombie request Again, as I've reported in http://www.freebsd.org/cgi/query-pr.cgi?pr=128076 , I was not using acd0 and I never did since the box had been turned on. The box was replying if pinged, but I was unable to access it via ssh, so I had to press the reset button. What happened is similar to what is described here: http: //lists.freebsd.org/pipermail/freebsd-ports/2006-December/037796.html And here http://www.freebsd.org/cgi/query-pr.cgi?pr=110015 I can see another swi6 panic with the same message in the kernel buffer (acd0: WARNING - PREVENT_ALLOW read data overrun 18>0) I had in pr. Isn't my backtrace of any help in tracking down the problem?
