"couldn't map interrupt" problems with updated 6.0 kernel

Mon Jan 30 21:48:16 PST 2006

Hi,

Since the FreeBSD src update I did tonight, my computer has problems 
with irqs. Before this update I was using 6.0-stable (built on Dec 9 
'05) and it was working fine with APIC enabled (device apic in kernel 
config file). Now when I enable APIC with the new kernel I get the 
following error messages at boot time:

Jan 30 22:19:59 ldaemon kernel: bge0: <Broadcom BCM5702 Gigabit 
Ethernet, ASIC rev. 0x1002> mem 0xd5000000-0xd500ffff irq 9 at device

and then the computer freezes. I have tried to do not load the sound 
card driver, but it didn't fix it. I have also tried to comment out 
"device apic" in the kernel config file. Now I do not get these error 
messages. Instead I get messages like this:

Jan 30 23:38:42 ldaemon kernel: rl0: watchdog timeout

and the ethernet cards don't respond properly.

With the Dec 9 kernel (where apic is enabled), I get the following at 
boot time:

I have used FreeBSD 4.x, 5.x and 6 in the past on this computer with 
exactly the same hardware configuration without any problem. How can I 
fix it?

Thanks!!
