card initialization on ipaq

Hi,

I'm testing hostap work with an Ipaq 3600 and a Netgear MA401 RA card 
(prism 2.5, PCMCIA)

When I insert the card in the adapter wlan0 is created but the driver 
can't initialize it. Below you have the dmsg dump:

-------------------------

hostap_crypt: registered algorithm 'NULL'
hostap_cs: CVS (Jouni Malinen <jkmaline at cc.hut.fi>)
hostap_cs: setting Vcc=33 (constant)
hostap_cs: CS_EVENT_CARD_INSERTION
hostap_cs: ignoring Vcc=50 (from config)

hostap_cs: Registered netdevice wifi0
wifi0: Interrupt, but dev not OK
hostap_cs: index 0x01: Vcc 5.0, irq 42, io 0xcaa60000-0xcaa6003f
wifi0: init command completed too quickly - retrying
prism2_hw_init: initialized in 0 ms
prism2_enable_aux_port(1) timed out
prism2_enable_aux_port: was not enabled!?
wifi0: valid PDA not found
SWSUPPORT0 write/read failed: 0000 != 8A32
hostap_cs: Initialization failed
prism2_config() failed

-------------------------

I'm able to setting up the card by manually performing an hardware reset 
("iwpriv wlan0 reset 1").
I have also to manually set the MAC address after the reset.

After this, the card seems to work quite normally with ligth traffic 
(ping), but when
I try to measure the card performance with netperf I get very low (and 
variable) throughput
(from 0.05 MB/s to 1.00 MB/s).

The card seems to be reset for transmission timeouts, as you can see in 
dmesg dump at the end of the mail.
I use hostap cvs version and Familar 0.7.2 distribution with a 2.4.19 
kernel.
I tried both f/w 1.3.6 and 1.7.4 with same results.

In attachment, you have also the ethereal capture of a netperf test (a 
simple TCP test lasting 10 seconds).

Do you have any suggestion, please?
Thanks and bye
Marco
