Hi,
i'm running a db800 board with a geode lx 700. Linuxbios os working well expection ethernet and the pci bridge.
The bride chipset will be detected by lspci: 00:0e.0 PCI bridge: Hint Corp HiNT HB4 PCI-PCI Bridge (PCI6150) (rev 04)
Also the wireless card which is inserted into the pci-bride is detected by lspci. When loading the driver for the wireles card the following message is showed in dmesg: -------------------- ath_pci: 0.9.4.5 (0.9.3.2) PCI: No IRQ known for interrupt pin A of device 0000:01:0f.0. wifi%d: request_irq failed --------------------
When i use the normal bios which is shipped with the hardware - it works.
Lspci -vvv also says "Interrupt: pin A routed to IRQ 0" (for the wifi card). Seems that it is the problem but what can i do now?
