Hi,
I have a PCI hardware modem card "Agere Systems Venus Modem (V90,
56KFlex)". This has been working fine with FC4. However on updating
to the 2.6.16-1.2069 kernel it stopped working.
It does not work with the 2.6.16-1.2096_FC4 kernel also.
There is a message in /var/log/messages:
"Couldn't register serial port 0000:05:01.0: -28"
Any ideas if this is a bug or a kernel change ?

I have found that I can add the kernel boot option "8250.nr_uarts=4"
which gets around the problem. I presume the number of serial ports to
determine at boot time was configured to 2 in this release of the kernel.
1. Should the default number of seerial ports configured at boot time be
increased ?
2. Should the hotplug system handle adding the PCI serial card at runtime ?
Cheers
Terry
