Hi all,

I've been debugging this issue for days now , but can't figure it out :
My system is based on mpc8248 by freescale , and I'm using kernel 2.6.29.4 with Xenomai 2.4.8 . I have 2 serial devices receiving simultaneously .
When using Baudrate 115200 problems occure - I get errors in the data received . (this doesn't happen when receiving only on one port at a time in this BAUDRATE) , but also doesn't occure when receving on both simultaneously on BAUDRATE- 38400 . When the error occures I get (sometimes , but not always - "No room in flip buffer"
and also I get error - EAGAIN  from the   "nread = read() "  function .
And while getting EAGAIN I also get a possitive retrun value (nread) .
Ideas are welcome .

Ideas are most welcome !
Thanks,
Yigal Goldberger.
