Hi,
I was trying to test miniPCI atheros-based card in wrap, using 7-CURRENT. Some
time ago, it attached as ath0, I did some configuration and it looked OK.
Yesterday, I tested it again with system built from sources cvsupped at May
12. No attachment, pciconf -lv said (relevant device)
none0@pci0:13:0: class=0x020000 card=0x00000000 chip=0xff16168c rev=0x01
hdr=0x00
vendor = 'Atheros Communications Inc.'
class = network
subclass = ethernet
From some earlier conversation I got chips with ID beginning 0xFF are
pre-production and should not be used.
Just out of curiosity I put this card in my tablet TC1000, with system built
from sources cvsupped at May 15 and got
ath0@pci0:10:0: class=0x020000 card=0x000d17f9 chip=0x001b168c rev=0x01
hdr=0x00
This makes me wonder - how could the same card be identified as two different
devices? I tested the same card, then another one and the result is the same.
Working in my tablet, not working in WRAP. There is one difference, however -
kernel in WRAP has ath built-in, in my tablet I am kldloading it.
If it were the other way round, I would be happier - I can use those cards for
some radio links, but it would not be less surprising.
Any ideas?
Regards,
Milan
