>Description:
If PUC device is not included on a system with a PCI modem
or serial port (SIO device), the serial port will commandeer
the IRQ, causing any other devices sharing the IRQ to fail
to initialize.
This can cripple the booting system to the point the only
work around is physically ripping the offending device out.
Note that a PCI SIO device cannot be disabled by the user
kernel configuration screens, so this problem can be prevent
a binary install of of the system if the modem and disk
controller are sharing an IRQ.
This can prevent FreeBSD installation.
>How-To-Repeat:
Boot a reasonably equipped system with a PCI hardware modem
installed using the FreeBSD install CD with the GENERIC
kernel.
>Fix:
Add PUC device to GENERIC kernel so devices are not disabled
during and after install by poor IRQ management.
