This happened on amd64 with sources from first week of= =20 may. I got it on 20-30 days uptime untouched smp dual-core amds and two=20 opteron server. On all of them acpi-fast seems to be the counter. Anyway I= =20 did a cvsup and haven't seen the problem again so far. I did't get any=20 message before, the first caused a panic and funny all panics happened almo= st=20 the same hour last friday. =2D-=20 Jo=C3=A3o A mensagem foi scaneada pelo sistema de e-mail e pode ser considerada segura.
