Well, the the detection of an unclean shutdown is somewhat broken or the FreeBSD driver isn't able to shutdown the controller properly in some cases. I saw this behaviour mostly, if the machine is powered down (for example by "shutdown -p"). If I just reboot (new kernel or so), then I nearly never saw that behaviour. I have seen this on twe cards, which don't even have own RAM, so that it's unlikely that the buffer was not cleared. The message, that the controler has been shut down by FreeBSD always showed up in those cases. On the other hand, I have machines (other motherboard/chipset/BIOS), where I never saw that behaviour. There is/was definitely some strangeness in that, but I cannot tell, if it's still in recent versions of FreeBSD (machine was not switched off for some time, it's in Production). The behaviour is most likely dependent on the ACPI (read: ACPI BIOS of the machine) or anything else related to the hardware and I'm not even sure, if FreeBSD's driver could do anything about it. The inialize state is already shown in the BIOS, if FreeBSD could do anything, then it would be in the controler shutdown procedure. - Oliver -- | Oliver Brandmueller | Offenbacher Str. 1 | Germany D-14197 Berlin | | Fon +49-172-3130856 | Fax +49-172-3145027 | WWW: http://the.addict.de/ | | Ich bin das Internet.
