Description of problem:
After updating to kernel-2.6.9-1.724_FC3, pci modem configured to
ttyS14 instead of ttyS4. That seems to confuse kudzu.
/dev/modem is not being configure at boot, which in turn breaks
all dial-up configurations...
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.boot to kernel-2.6.9-1.724_FC3
2.check for /dev/modem
Actual Results: is not there. Actual modem configure to /dev/ttyS14
Expected Results: Modem at /dev/ttyS4. Kudzu (?) sets /dev/modem ->
Athlon XP, Asus A7V333 m/b, USR 56k Internal Voice Modem (Model 2976)
(output of "lspci -vvv" is attached)
Created attachment 109412 [details]
output of lspci -vvv with 2.6.9-1.681_FC3 kernel
OK. I did cold reboot (power cycle) and let kudzu unconfigure and
then reconfigure modem. That created /dev/modem. Then I discovered that
"neat" uses /dev/ttySX device instead fo /dev/modem (kudzu buglet?).
After manually changing that, everything seems to be working again.
I still not sure this (change ttyS4 -> ttyS14) is a desired behavior,
so will live it open but at lower priority.
My modem is also now /dev/ttyS14. I have an actiontec call waiting
modem (internal pci). Kernel 2.6.10-1.741_FC3 still has this
behavior. My modem has been /dev/ttyS14 since 2.6.10-1.737_FC3 and

An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which
may contain a fix for your problem. Please update to this new kernel, and
report whether or not it fixes your problem.
If you have updated to Fedora Core 4 since this bug was opened, and the problem
still occurs with the latest updates for that release, please change the version

It looks OK in FC4
