Comment(by BillK):

 Flashed shr-unstable last night (built locally - 10th April) - 2.6.29
 kernel

 Never was able to talk to the GSM over many attempts using the mux - often
 got this error:

 Apr 10 19:43:59 om-gta02 user.debug kernel: [  185.015000] modem wakeup
 interrupt
 Apr 10 19:44:04 om-gta02 user.debug kernel: [  189.830000] rxerr: port=0
 ch=0x00, rxs=0x0000000c
 Apr 10 19:44:04 om-gta02 user.debug kernel: [  190.075000] modem wakeup
 interrupt
