Driver bug !!

[Rajashekhar Mansanpally]

My current configuration:
----------------------------------
wlan1: NIC: id=0x800c v1.0.0
wlan1: PRI: id=0x15 v1.0.7
wlan1: STA: id=0x1f v1.7.4

I am using 'Zcomax' card

dmesg ouput:
------------

wlan1: driver bug - prism2_transmit() called when previous TX was
pending
wlan1: prism2_tx - to BAP0 failed
wlan1: scheduled card reset
hostap_cs: wlan1: resetting card
prism2_pccard_cor_sreset: original COR 41
prism2_hw_init: initialized in 250 ms
wlan1: trying to read PDA from 0x007f0000: OK

And almost always is followd by:
-------------------------------
wlan1: CMD=0x0121 => res=0x7f, resp0=0x0004
wlan1: hfa384x_set_rid: CMDCODE_ACCESS_WRITE failed (res=127, rid=fc43,
len=2)
wlan1: cnfEnhSecurity setting to 0x0 failed

** This seem to be triggered if I have more than 3-4 clients.
Currently I 've all sony clie clients.

I 've seem couple of guyz asking similar questions. But no replies.
I want to try my luck. I hope someone has an idea to get around
this.

TIA
