No wlan after kernel update, Broadcom 43

[amityak]

Hello People!

I've recently reinstalled ubuntu 7.10, thats because i thought it would ran frictionless. It actually did work almost perfect from the box (except for some xorg.conf twiches)

It installed almost automatically the needed firmware for my BC4318 and all was goody good.

Then i did some updates including the kernel to 2.6.22-15

since then wireless stops responding.

As i have no LAN connection but just wireless at home i reboot to the 14 version and now its working fine.

any ideas what might have gone wrong?


####SOME MAYBE NECCESARY QUETES:####

lspci:

00:06.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02)
Subsystem: Unknown device 17f9:0006
Flags: bus master, fast devsel, latency 64, IRQ 20
Memory at d0000000 (32-bit, non-prefetchable) [size=8K]


ill try to get now the iwconfig output from the kernel version 15 and then reboot to report if here.

Thank you all!



###EDIT### ::

Been back from the darkness and here are the outputs from the newer kernel:

jts@jake:~$ iwconfig

I'm interested in your problem. It seems that you may have been bitten by a bug related to an SPROM coding problem. If you want to help, please run the following commands in a terminal with module ssb loaded:

SPROM=$(find /sys -name ssb_sprom)
echo $SPROM

The first of these may spit some warnings, but as long as the second looks something like /sys/devices/pci0000:00/0000:00:0d.0/0000:04:00.0/ssb_sprom
it is OK. Next do

sudo cat $SPROM > sprom.dat

This will read out the contents of your SPROM. Please post the contents of sprom.dat here, or attach the file.

BTW, wht brand does this card have on it? The official list of PCI vendors does not contain the code 0x17F9.
