 Posted: Mon Jan 19, 2004 6:20 pm Post subject: Linux 2.4.22 broke my wireless LAN setup |
 |
|
I use an Edimax EW-7105PC wireless LAN PCMCIA card on my laptop. It's been working fine with the Atmel driver version 2.1.2.2 and Linux kernel version 2.4.20.
Last time I ran emerge -u --deep world (stable tree) I got the 2.4.22 kernel. After compiling the new kernel with the same configuration and rebooting the LAN wouldn't start up.
The problem seems to be related to the Atmel module pcmf502rd.o. When loaded it gives the following messages:
| Code: | > modprobe pcmf502rd
/lib/modules/2.4.22-gentoo-r2/pcmcia/pcmf502rd.o: unresolved symbol ether_setup_R3gig_28f37dda

I tried recompiling the Amtel driver against the new kernel. I also tried downloading and compiling the latest version 3.2.4.4. No difference.
When I reboot the old kernel everything works fine.
Am I missing some new kernel option? |

Hmmm.... I use the same drivers and have had problems when upgrading my kernel as well. Before we delve into whether your kernel is configured correctly, let's see make sure you've compiled the modules correctly against the new kernel.
You should have to:
link /usr/src/linux to your new kernel sources directory
reboot with your new kernel
go to your atmel source directory
make realclean
make config
make all install
Are you following all of these steps? If so, we'll see if there's anything else you need to do. |

I was about to answer that I had tried all your suggestions but I decided to double check just to be sure. Just as well i did. I went through it again as you suggested an this time it worked! 
The only thing I hadn't done is the make realclean step. I ran make clean instead. There must have been on old .config file in the driver source tree.
Thank you very much for your help. |
