Hi,
whenever I try to set my mini PCI-e card (Anatel AR5BXB6) as Master
(tdmaslot 0), kernel shows PANIC msg like the below.
It's OK when I set the card as not Master like tdmalsot 1,2, and more. What
is the problem? And how can I fix it?
Interestingly, the kernel PANIC occurs when I use this card with IBM T60.
When I use this card with IBM T61, there is no PANIC message like the below.
Instead, kernel shows never ending "Ath0: Stuck beacon; bmiss..." messages.
How can I solve the problem? I searched but it is hard to find the answer
for my cases.
Thank you and I expect wise solutions.
K.
