Subject: possible Bug in IOAPIC concerning serial 8250
Hello,
i know, no good place to start, but my problem is a little bit
unspecific concerning Problems with IOAPIC concerning serrial driver
8250 :
1. serial driver 8250 is loaded, but /dev/ttyS0 is unusable
2. hardware is a d945gclf2 mini-itx board from intel, distribution is
easyvdr 0.6.06., Kernel Version is 2.6.29.3, serial port is activated in
BIOS, BIOS rev LF94510J.86A.0171.2009.0403.0118
dmesg reports :
[ 21.682611] Serial: 8250/16550 driver, 1 ports, IRQ sharing disabled
[ 21.682789] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
[ 21.711689] 00:09: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
and lsmod :
8250_pci 27412 0
8250_pnp 14036 0
8250 20516 2 8250_pci,8250_pnp
serial_core 18708 1 8250
so driver is loaded
ls -lpr /dev/ttyS0
crw-rw-rw- 1 root tty 4, 64 2009-06-03 07:55 /dev/ttyS0
seems ok to me
but cat < /dev/ttyS0 gives :
cat: -: Eingabe-/Ausgabefehler (I/O Error)
/proc/interrupts is missing driver for irq4 :

If you need more information, let me know. Perhaps you have ideas, what

for serial port. Or ACPI doesn't find the parameters.
