problems with multitech 4 port serial card under 2.4.x and 2.6.x

problems with multitech 4 port serial card under 2.4.x and 2.6.x

[John Covici]

I have had problems with the multitech 4 port serial card under both
the 2.4 and the 2.6 Linux kernels.

I guess the most important problem is that the driver module does not
detect the card at all -- the only driver whichworks is the one from
multitech itself.   Here is the lspci -v entry for the card.

0000:00:0e.0 Serial controller: Exar Corp. XR17C158 Octal UART (rev
01) (prog-if 02 [16550])
        Subsystem: Unknown device 2205:2001
        Flags: fast devsel, IRQ 7
        Memory at fba00000 (32-bit, non-prefetchable) [size=2K]
 
Now also, I have an Asus a8V and if I have the apic support for uni
processors on it won't even boot with the card installed.

Any assistance on these matters would be appreciated -- especially

You don't say which 2.6 kernel.  Support for these UARTs has only
recently been merged - you'll find it in 2.6.9-rc2 kernels.

Unfortunately I don't recall if it's in 2.6.9-rc1 or not.

Well, I was using 2.6.8 and there is under character devices a
configuration which says multitech and it says its experimental, but
it does not detect the card -- same with 2.4.26.  Maybe I should try
the rc2 and see if my apic problems go away as well -- which would be
nice.

I found it in the changelog -- thanks much.  I wonder why the board
would freak out the apic stuff?
