Hello There!
	I'm using hostap_cs in a embedded linux board (Motorola's FADS) with kernel 
2.4.20-pre11 and pcmcia-cs 3.1.22 or pcmcia-cs 3.2.3. After compiling 
everything without a glitch and loading up all modules, a win2k laptop is 
able to connecto to my acess point. After some ramdom time, I get the 
following message:

# NETDEV WATCHDOG: wlan0: transmit timed out
wlan0 Tx timed out! Resetting card
hostap_cs: wlan0: resetting card
wlan0: Interrupt, but SWSUPPORT0 does not match: 0000 != 8A32 - card removed?
wlan0: Interrupt, but SWSUPPORT0 does not match: 0000 != 8A32 - card removed?
wlan0: Interrupt, but SWSUPPORT0 does not match: 0008 != 8A32 - card removed?
wlan0: Interrupt, but SWSUPPORT0 does not match: 0000 != 8A32 - card removed?

While loading, the hostap shows these messages:

hostap_cs: index 0x01: Vcc 5.0, irq 9, io 0x0100-0x013f

Cat on /proc/interrupts:

# cat /proc/interrupts
           CPU0
  5:        630   8xx SIU   Edge      cpm
  9:         24   8xx SIU   Edge      hostap_cs
 11:          0   8xx SIU   Edge      m8xx_pcmcia
 15:          0   8xx SIU   Edge      tbint

The time to the error is random, sometimes I'm able to download some data (1 
meg), sometimes it takes just a sec to give the error. I've already read some 
messages on the list about similar errors, but of them refers to PCI boards, 
not PCMCIA. Any help is greatly appreciated!
