Well brian there is way to allot IRQ's but not for IRQ 7 as there was
notthing mentioned in front. It is saying that select yes or no in bios. I
did 'yes' and tried but still irq 7 (spurious irqi 7 came) with linksys wpc
11 card.
Well but i find something interesting though, that if i try to load NETGEAR
card which is again 5.0 card by doing .
modprobe hostap
modprobe hostap_cs ignore_cis_vcc=1
and now push the card in the socket.
Do dmesg:
No SPURIOUS IRQ 7 is found. But still the system hangs after abt some 20-25
sec.I Cannot do "iwconfig" but ifconfig for some time works fine, after
that system halts or stalls.
Same with my earlier working, when i tried to load hostap using the above
procedure :senao NL2511 card(3.3V) , no spurious IRQ 7 was found, but again
the system just stalls. Nothing can be done except reboot.
Is this a hint to the right direction, is there is some hope :)
