Hello
I am having problems with my soundcard and my NIC on my toshiba portege
7140CT running woody 2.4.18. (My sound is jumpy and my NIC is sometimes
not identified- this may be related to the state of the sound device when
i power down, but i'm not 100% sure.)
I think this is due to them sharing an IRQ (along with several other
things, including video). The output of lspci and contents of
/proc/interrupts are below.
My question is: how do i assign different irq's to these devices?
My BIOS gives me the following 2 options:
Configuration: device config= "All devices" or "Setup in OS"
However, neither allows me to adjust the irq assigned to everything
other than parallel, serial, and modem. The floppy, HDD (ide0),
dock(ide1) and PCI bus have apparently non-configurable irqs in bios.
(The only difference between the options seems to be is that "All
devices" allows me to insist that PCIC is used for the PC card
controller mode)
Kernel options presently set as
CONFIG_PCI=y
# CONFIG_PCI_GOBIOS is not set
# CONFIG_PCI_GODIRECT is not set
CONFIG_PCI_GOANY=y
CONFIG_PCI_BIOS=y
CONFIG_PCI_DIRECT=y
CONFIG_PCI_NAMES=y
Is APIC a solution, and how do i enable it if it is not enabled?
config:
CONFIG_X86_GOOD_APIC=y
CONFIG_X86_UP_APIC=y
CONFIG_X86_UP_IOAPIC=y
CONFIG_X86_LOCAL_APIC=y
CONFIG_X86_IO_APIC=y
but in dmesg:
Local APIC disabled by BIOS -- reenabling.
Could not enable APIC!
(Also APCI is not running, but it think this doesn't offer a solution anyway)
Thanks in advance for any help.
