wlan0 disappears after few seconds [Hostap problem]

Hi,
I've installed hostap on a Gentoo Linux box with kernel 2.4.31 (I need
to use a 2.4 kernel) and a Netgear MA401 PCMCIA card and everything
seems to work: I can change wlan0 to Master mode (even if I get an
error, as if the request was illegal, but then iwconfig shows me wlan0
and wifi0 in Master mode.. is it normal?) and other laptops are able
to connect to my laptop as if it was an access point (two laptops
associated themselves to my laptop and then they were able to ping one
each other).. The problem is that after few seconds something wrong
happens and the access point stops working (iwconfig tells me that
wlan0 has "no wireless extensions").. I'll put here the relevant
content of dmesg, perhaps some of you can help me (i need to make this
stuff work for my thesis):

wlan0: could not enable MAC port
wifi0: Command completion event, but no pending commands


Perhaps it's something related to the "MAC port 0 enabling failed" error...
Any idea?

Thank you in advance for any suggestion,
Gianni
