panic on sparc64 with oem fw pci fw card

Hi all,

I get the below panic when I load fw support on my sparc64.

I first posted this issue to the sparc64 list. Marius suggested to post 
to fw and simokawa@, here I do.

On suggestion of Marius I modified the fwohci.c with this:

Index: fwohci.c
===================================================================
--- fwohci.c	(revision 190571)
+++ fwohci.c	(working copy)
@@ -527,7 +527,7 @@
  		device_printf(dev, "resetting OHCI...");
  	i = 0;
  	while(OREAD(sc, OHCI_HCCCTL) & OHCI_HCC_RESET) {
-		if (i++ > 100) break;
+		if (i++ > 1000) break;
  		DELAY(1000);
  	}
  	if (firewire_debug)


Also, I hardcoded firewire_debug to 1 since sysctl does not work on not 
loaded modules.

I'm not able to cross debug since I build this kernel on a MacBook Pro. 
I have no second sparc64 available to kgdb the issue.

The kernel I run is the latest and GREATEST (svn r190571), note beside, 
hat off, you all, you provide a really cool and fine OS!

I'm happy to provide more details on request. Also, if you have some 
code changes, please.

TIA,
Andreas
