Hello world,
I have a Dell inspiron 910 with a Broadcom wireless card.
andy:~$ lspci -vnn | grep 14e4
03:00.0 Network controller [0280]: Broadcom Corporation BCM4312
802.11b/g [14e4:4315] (rev 01)
Subsystem: Broadcom Corporation Device [14e4:04b5]
Today I downloaded the current wireless-testing kernel (2.6.32-rc6-wl)
and compiled it without the ACPI kernel driver.
It worked well for about 15 mins but then the network connection was
lost and /var/log/sys.log started to fill up with
