Comment(by Sascha):

 I'm running debian with kernel 2.6.29 stable
 821e9fa664049b1e5e97a00f6eeed3b72b67c1ba on a GTA02v5 and I get lots of
 these error messages for GPS and GSM.

 For the attached syslog I've removed the trace in iblock.c (it doesn't
 work for me) and
 I've added the port number to the rxerr messages:

 {{{
 Feb  8 00:51:44 gta02 kernel: [  293.080000] rxerr: port=1 ch=0x45,
 rxs=0x00000001
 ...
 Feb  8 00:52:02 gta02 kernel: [  310.250000] rxerr: port=0 ch=0x7e,
 rxs=0x00000001
 Feb  8 00:52:02 gta02 /usr/sbin/gsm0710muxd[1598]:
 gsm0710muxd.c:1168:gsm0710_advanced_buffer_get_frame(): Dropping frame:
 FCS doesn't match
 }}}

 Oh, and hardware handshake is enabled:
 {{{
