Re: Boot time panic with latest Preview

[Matthew Dillon <dillon@xxxxxxxxxxxxxxxxxxxx>]

:	Hi,
:
:	Following the note that the Preview tag has been bumped I updated
:my sources today, built world and kernel (custom kernel config at
:ftp://sohara.org/pub/STEVE) rebooted and got a panic during the boot with
:the message below. I've put a full dmesg.boot from the box running the
:previous kernel at ftp://sohara.org/pub/dmesg.boot for reference. Hardware
:is an Asus A8V with a no name NGE based board installed and a Pinnacle/Miro
:TV tuner card.

    Maybe Sephe can work out what is going on here.  Somehow it is hitting
    a phy entry created at dev/netif/mii_layer/mii_physubr.c line 379.
    I don't know whether this is correct or not, but if it calls
    mii_phy_set_media() with that entry it will panic just as you have
    above.
