Perhaps it's time for more information.
Here's the things I've tried:
set hw.pcic.intr_path=1
Causes the "hang" to occur as soon as the card is
inserted, instead of when pccardd tries to read the CIS
set hw.pcic.intr_path=1
set hw.pcic.irq=10
IRQ=10 was the IRQ used under 4.1-RELEASE, setting
this (along with hw.pcic.intr_path=1) causes a panic
at boot:
pcic0: PCI Memory allocated: 0x44000000
pcic0: Can't route ISA CSC interrupt
panic: resource_list_release: can't find resource
set hw.pcic.irq=10
Without setting hw.pcic.intr_path=1, the machine
will boot - but the IRQ used for pcic0 is 9, here's
the messages:
pci_cfgintr_liked: linked (60) to hard-routed irq 9
pci_cfgintr: 0:12 INTA routed to irq 9
pcic0: <Ricoh RL5C478 PCI-CardBus Bridge> irq 9 at device 12.0 on pci0
pccard0: <PC Card bus (classic)> on pcic0
pci_cgintr_linked: linked (61) to hard-routed irq 9
pci_cfgintr: 0:12 INTB routed to irq 9
pcic1: <Ricoh RL5C478 PCI-CardBus Bridge> irq 9 at device 12.1 on pci0
pcic1: PCI Memory allocated: 0x44001000
pccard1: <PC Card bus (classic)> on pcic1
And - when I insert the card, I get the hang.
The messages I see are:
pccard: card inserted, slot 0
pccardd[41]: Card "PCMCIA"("FastEhternet") [V] [1.0] matched "PCMCIA"("FastEthernet") [(null)] [(null)]
ed1 at port 0x300-0x31f irq 9 flags 0x30000 slot 0 on pccard0
***hang***
<then, remove card>
-beeps (both the inserting & removing beeps) -
ed1: address 01:02:00:ff:15:12, type NE2000 (16 bit)
ed1: SmartLink inserted.
ed1: detached
pccard: card removed, slo 0
ed1: SmartLink removed
"default" kernel (no setting):
same messages/behaviour as the hw.pcic.irq=10 case
I'm wondering if this "hard-routed irq 9" is the culprit, as
I'm pretty sure it should be irq 10. Does that come from a
kernel config?
And - I'm pretty handy at debugging the kernel, if you could
just point me to the area, I can sprinkle some printf()s around
to see where the hang occurs.
- Many Thanks for all your help! -
