Hi there,
I'll apologise now, this is the first kernel-related issue i've ever
experienced, so I may be doing this wrong or missing something :).
I recently downloaded and compiled 2.6.20-rc1 and set it up nicely with
my zd1211 card (Addon ADD-GWU180) and now the kernel oops's on boot in
normal mode, or when issuing "iwconfig eth1 essid essid_name" in
recovery mode. From the information it spews out at the time, it looks
like possibly a ieee80211softmac issue, but it doesn't happen with an
rt2570 card, and I thought it best to check with you first.
Hopefully all the information you need is included below, if not, i'll
be happy to provide anything else you need.
Thanks in advance.
