Takze prvni vec: parametr pci=biosirq nefunguje dmesg vzdal napady a proste ohlasi, ze irq se nekona:

PCI: Enabling device 0000:00:02.7 (0000 -> 0001)
PCI: No IRQ known for interrupt pin C of device 0000:00:02.7.
unable to grab IRQ 0

dalsi vec - /dev/dsp

[root@Alena drom]# ls -l /dev/dsp
ls: /dev/dsp: No such file or directory
[root@Alena drom]#

Takze neni.

jeste jsem objevil jednu zahadu s IRQ v dmesg:

[root@Alena drom]# dmesg |grep PCI:
