[Madwifi-users] null pointer dereference on 2.6 with HEAD

[Santiago G. M. <ma...@ma...>]

Hi!

I've tested HEAD as of some minutes ago to see if the lasts commits had
fixed the problems with 2.6 but it seems that it hasn't, I'm still having
problems in a machine setup as AP when continuously downloading things from
a client to the AP at full speed.

This is the dump I'm getting from the kernel:

Unable to handle kernel NULL pointer dereference at virtual address 00000088
 printing eip:

If anybody can have a look at this, please let me know if he needs anything
else or any testing or whatever.
