Hi!

I`m trying to suspend a1200 with "echo mem > /sys/power/state" and getting this:

http://pastebin.com/fe222ff7

looks like happened two things:

1) bp awaked ap just after sleep
2) bp paniced or lost from ap after resume

after reading  ohci-pxa27x.c and old ipc driver i see following:

* old driver suspends port when no data transmited during some timeout
* in new driver we disabled this behaviour and leaving suspend to hci driver
* hci driver not suspends ports, it stops and resets whole hci
* bp requires some actions to keep working after ap sleep
* there is also ap_rdy, which is used to wake up and for handshake and
  commented out gpio_set in ezx-bp driver.

i`l try to shut up modem with AT+CMER=0,0,0,0,0 and set ap_rdy to 0 before sleep
and set ap_rdy to 1 at resume. is this ok?
