[Atmel-WLAN-USB] Berlios driver and debian 2.4.20-i586-tsc (was Re: Kernel error)

[Florin Buzesteanu]

Hi Joerg,

I got the problem under debian i have looked at the Makefile in the 
Berlios drivers and have see that this:
-----------------------------------
KERNEL_SRC = /lib/modules/$(KERNEL_VERSION)/build
KERNEL_HEADERS = $(KERNEL_SRC)/include
-----------------------------------

can not match on my System, so i have do an link with:
-----------------------------------
ln -s /usr/src/linux /lib/modules/2.4.20-1-586tsc/build
-----------------------------------
because the build directory is not there, and now the drivers work perfect
and since 2 days i have no kernel crash.

so a very big thx for your help.
