bluetooth cf slow (10KB/sec), lots of dmesg spam

[Pavel Machek]

Hi!

I'm using CF bluetooth card:

toy:~# setserial -av /dev/ttyS0
/dev/ttyS0, Line 0, UART: 16950/954, Port: 0xc48202f8, IRQ: 201
	Baud_base: 921600, close_delay: 50, divisor: 0
	closing_wait: 3000
	Flags: spd_normal skip_test

toy:~# hciconfig
hci0:	Type: UART
	BD Address: 00:10:60:AB:25:9A ACL MTU: 192:8 SCO MTU: 64:8
	UP RUNNING PSCAN ISCAN 
	RX bytes:1612262 acl:5084 sco:0 events:3602 errors:0
	TX bytes:507156 acl:3779 sco:0 commands:28 errors:0


...and it mostly works, but slowly, and with tons of complains. Card
is:

toy:~# lspcmcia -v
Socket 0 Bridge:   	[pxa2xx-pcmcia] 	(bus ID: pxa2xx-pcmcia)
	Configuration:	state: on	ready: yes
			Voltage: 3.3V Vcc: 3.3V Vpp: 0.0V
Socket 0 Device 0:	[serial_cs]		(bus ID: 0.0)
	Configuration:	state: on
	Product Name:   Compact Flash Bluetooth Card 
	Identification:	manf_id: 0x0279	card_id: 0x950b
			function: 2 (serial)
			prod_id(1): "Compact Flash" (0x95521410)
			prod_id(2): "Bluetooth Card" (0x7664fb1d)
			prod_id(3): --- (---)
			prod_id(4): --- (---)

I believe the problem is 115200 bitrate between system and CF serial;
I did setserial baud_base 921600,  but that does not seem to speed it
up. Do I need to do some special magic to enable high speed?

Any ideas?
