There is something different about BCM4306, rev 2 chips. I have the same chip
in my Linksys WPC54G
card. On my interface, the mac_suspend routine works correctly most of the
time, but it will
sometimes fail with a "MAC suspend failure" message. The system will go for
several hours without
getting any of these, then get several in a row. On my system, these are
usually not fatal.

These are normal. Ignore them.

I would stay away from monitor mode at the start. I would bring the interface
up with an 'ifup eth1'
command, then check if it will scan by issuing an 'iwlist s' command. Your AP
should be on at this
point. The reason that the cpu is at 99% is due to the loop in
bcm43xx_mac_suspend.
Before you run another test, please apply the following patch:
index 3889f79..c40609c 100644
--- a/drivers/net/wireless/bcm43xx/bcm43xx_main.c
+++ b/drivers/net/wireless/bcm43xx/bcm43xx_main.c

+ printkl(KERN_ERR PFX "MAC suspend failed with IRQ_REASON =

}
void bcm43xx_set_iwmode(struct bcm43xx_private *bcm,
I generated this patch from v2.6.18-rc2 so there may be some offsets, but the
resulting output
should show why your interface will not suspend the MAC.
After you rebuild bcm43xx.ko, please run the iwlist test and send the results
back to me.
