Network issues from suspend and resume

F

flce

I own a Dell Inspiron 1318. Suspend to RAM is working almost perfectly for my computer. Everything is working upon resume except my network interfaces. The network interfaces cannot be started up again.

I am running:

Code: 
FreeBSD local 8.2-RELEASE FreeBSD 8.2-RELEASE #6: Sun Apr 24 07:54:36 EDT 2011 amd64

Interfaces from ifconfig:

Code:

From before resume, pciconf -blcv:

ecap 0002[13c] = VC 1 max VC0
ecap 0003[160] = Serial 1 00219bfffedcf958

After wakeup, pciconf -blcv:

Code: 
wpi0@pci0:12:0:0:       class=0x028000 card=0x135b103c chip=0x42228086 rev=0x02 hdr=0x00

    device     = 'Intel 3945ABG Wireless LAN controller (10208086)'
    class      = network
bge0@pci0:9:0:0:        class=0x020000 card=0x02861028 chip=0x171314e4 rev=0x02 hdr=0x00
    vendor     = 'Broadcom Corporation'
    device     = 'Broadcom NetLink (TM) Fast Ethernet (BCM5906m)'
    class      = network
    subclass   = ethernet

Relevant parts posted. All the other PCI devices are mostly Intel stuff under PCI domain 0.

The bar, cap, and ecap data is completely wiped out for the network devices only. The network kernel modules refused to attach and sometimes would cause the kernel to panic. However, everything else is working fine.

I have been searching online for various states in hw.acpi, debug.acpi, and hw.pci to change. While most of the ones I have tested have shown no difference, setting debug.acpi.suspend_bounce to 1 allowed me to resume from a mock suspend without any issues.

As a result, I'm thinking of modifying the asl to get networking working and would like to find some advice on how to do this. I have been following the instructions from the ACPI section of the FreeBSD Handbook. I have attached the output of acpidump. Although I have tried to fix the obvious errors and rebuild with iasl, the final .aml still does not resume network interfaces properly.

Has anyone else experience this issue and have a solution or some advice on how to approach this? Thanks in advance.

Thanks for your help, I actually came across those links as I was searching for a solution.

It turns out that the problem has been fixed in FreeBSD-current.
 
Everything is working now. As far as I know, only bge and wpi was causing problems before.
