Hi,
While attempting to use pci=biosirq kernel parameter in 2.4.3pre6 (same observed with ac20) I've got the following oops (manually rewritten) during 3c59x network adapter (compiled into kernel) initialization:
Unable to handle kernel paging request at virtual address 0000dde5 printing eip: c00fde03 *pde = 00000000 Oops: 0000 CPU: 0 EIP: 0010:[<c00fde03>] EFLAGS: 00010292 eax: 00000009 ebx: 0000dde5 ecx: 00000c0a edx: c1170cc9 esi: c02964f0 edi: 00000000 ebp: 00000000 esp: c1177e92 ds: 0018 es: 0018 ss: 0018 Process swapper (pid: 1, stackpage=c1177000) Stack: 00000cc9 64f00000 0000c029 7eb40000 0030c117 def80000 0c0ac117 0cc90000 deba0000 0000c00f 64f00000 0000c029 7ed80000 0030c117 0c010000 0c0ac117 b10c0000 dd410000 b10fc00f 0c0a0c00 c00fdba2 eecc0206 0010c010 000c0000 Call Trace: [<def80000>] [<deba0000>] [<dd410000>] [<eecc0206>] [<f32f0000>] [<f523c117>] [<def8c029>]
[and long, probably infinite trace here...]
Unfortunately ksymoops tracing gives no effect as the problem seems to appear in a BIOS call. Some printk() debugging shows trace:
vortex_init() ... vortex_init_one() [ drivers/net/3c59x.c ] pci_enable_device() [ drivers/pci/pci.c ] pcibios_enable_device() [ arch/i386/kernel/pci-pc.c ] pcibios_enable_irq() [ arch/i386/kernel/pci-irq.c ] pcibios_lookup_irq() [ arch/i386/kernel/pci-irq.c ] [ pci-irq.c:555: r->set(pirq_router_dev, dev, pirq, newirq) ] pirq_bios_set() [ arch/i386/kernel/pci-irq.c ] pcibios_set_irq_routing(..., 0, 12) [ arch/i386/kernel/pci-pc.c ]
What is the reason of this situation: 1. pci=biosirq option is generally broken, 2. my BIOS is not compatible with pci=biosirq kernel parameter, 3. pcibios_set_irq_routing() call with pin=0 is incorrect, 4. ... another problem ?
My PCI bus works at 30MHz and its configuration:
