Description Vladimir N.Chernenkov 2007-02-14 09:45:06 UTC 
Description of problem:

If actual size of memory on motherboard is <=1024M 
the all work OK. You may boot kernel-2.6.19-1.2895.fc6 with mem=1024M and
bigger phyzical size of memory, then working ok too.
But for default loading of the kenels up to kernel-doc-2.6.20-1.2922.fc7 with
size of memory > 1G there is crashed by error in DMA operations.

Version-Release number of selected component (if applicable):
kernel-2.6.19-1.2895.fc6.x86_64, 
kernel-2.6.20-1.2922.fc7.x86_64

How reproducible:
Build the system with CPU AMD Opteron and 2048M of memory on
ASUS SK8N Motherboard with PCI TEW-403PI wireless adapter.

Steps to Reproduce:

1. Configure WiFi device BCM4306 802.11b/g with wpa_supplicant as eth1
2. modprobe bcm43xx 
3. service wpa_supplicant start
