Hi!

It seems this commit

commit 7a56aa45982bb87bfca98a2832b5ae782c03364a
Author: Yegor Yefremov <yegor_sub1@xxxxxxxxxxxxxxxx>
Date: Wed Jun 16 16:29:55 2010 +0200

serial: add UART_CAP_EFR and UART_CAP_SLEEP flags to 16C950 UARTs
definition

Adding UART_CAP_EFR and UART_CAP_SLEEP flags will enable sleep
mode
and automatic CTS flow control for 16C950 UARTs. It will also
avoid
capabilities detection warning like this:

"ttyS0: detected caps 00000700 should be 00000100"

...is responsible for my bluetooth problems on zaurus -- at least
bisect pointed to it, as I use 16C950-based bluetooth card, it seems
very logical. I'll try 2.6.37-rc8 with that patch reverted...
