Hi Roger,
try to change flow control to soft.
Upon the change both minicom and hylafax communicate with the modem
well.
Why hardware control is down is another story.

Hi Roger,
if you saw "nobody cared about irq 16" after the same boot you made the above
printing, then you have problem with your USB controller too.
I am going to launch Ubuntu Live CD 10.04 with kernel 2.6.x to check IRQ
handling with those kernels.
Will share results here.
Regards

What you see in grub DEAFAULT command line at boot time is taken from
GRUB_CMDLINE_LINUX_DEFAULT
What you see at another grub menu item's command line (e.g recovery mode, or
another kernel version) is taken from GRUB_CMDLINE_LINUX.
What is there more is "pure linux meet", it is kernel image name
Do you have UEFI bios?
Can't follow "But since the boot line and the file info is different".
What is file info?
My modem is internal, PCI, has 16550A port built-in. It is ttyS4.
It doesn't matter what IRQ has my sound card uses, because IRQ sharing between
modem ans sound card is in your machi
Both you and me we do have new mobos. Yours is decent Intel piece, mine
decent AMD one. One clue more to look for problem source on operating
system's side.
Dont worry about system boot upon GRUB_CMDLINE_LINUX... change. You can
always play with kernel options at boot time and revert changes.

Roger,
GRUB_CMDLINE_LINUX_DEAFAULT attaches its options to default GRUB menu item only.
GRUB_CMDLINE_LINUX does it for each item (recovery modes too).
Since you can edit GRUB item line at while boot time, it is up to you which one
to choose.
But there is no reason to change any of those lines if
1. Reboot the machine
2. Press ESC upon GRUB menu appeared
3. Press "e" to enter edit mode of GRUB command launching kernel
4. find line with kernel options - it should contain one or more words "quiet",
"splash", "image"
6. fix cursor at the and of the line and enter "pci=routeirq" (w/o quotes)

Hi Roger,
finally solved similar problem with my server. The solution is to add kernel
option "PCI=routeirq" while booting (for test if works) and if it does to
GRUB_CMDLINE_LINUX in /etc/default/grub. Then run "update-grub".
My GRUB_CMDLINE_LINUX parameter is as follows:
GRUB_CMDLINE_LINUX="82
