Hello,

I've Interupt problems with shared interrupt and ICH4 chipset and a pnpbios

My problem is the follow. I've a box with ICH4 Chipset. The ttyS2 and
ttyS3 are conneted to the irq 10. 
After startup the box and using udev the module 8250.ko and
8250_pnp.ko are loaded.

I've tested with the 2.6.22.1 kernel. 

cat /proc/tty/driver/serial

0: uart:16550A port:000003F8 irq:4 tx:0 rx:0
1: uart:16550A port:000002F8 irq:3 tx:0 rx:0
2: uart:16550A port:000003E8 irq:10 tx:0 rx:0 CTS|DSR
3: uart:16550A port:000002E8 irq:10 tx:0 rx:0 CTS|DSR
4: uart:16550A port:000004F8 irq:10 tx:0 rx:0
5: uart:16550A port:000004E8 irq:10 tx:0 rx:0
6: uart:unknown port:00000000 irq:0
7: uart:unknown port:00000000 irq:0


when I user ttyS2 and ttyS3 seperatly it work's. When I use the ttyS2
and ttyS3 in the same time: ttyS3 generates Interrupts ttyS2 not.

I've tested with the follow sequences:

 ( for i in `seq 1 20` ; do printf "%x 01234567890123456\n" $i; sleep 2; done; ) > /dev/ttyS3

and 

 ( for i in `seq 1 10` ; do printf "%x 01234567890123456\r\n" $i; done;) > /dev/ttyS2

in the same time.

The output-sequence ist first the ttyS3 output then the ttyS2 output with a 2 second stepping.

I've make debug outputs for serial_in and serial_out, and I cann see that ttyS2 generates no
interrupts.

When I cancel the ttyS3 script the output fron ttyS2 are without delay's.
When I reload the 8250_pnp.ko module it works.

When I disable acpi, the serial ports are not found. 

Has anyware the same Problem?
