SiRF-2 stopped working in 2.38

[Sascha Silbe-74]

Finally managed to find time to narrow down the problem and post a bug
report.
gpsd stopped getting location information from my SiRF-2 based GPS mouse
between 2.37 and 2.38. Looks like it's always switching back and forth
between NMEA and SiRF binary.
Output of gpscat / gpspipe is at [1-3] for 2.37 resp. [4-6] for 2.38.
Looks like I haven't captured the debug output of gpsd, but maybe the
dumps are enough to figure out the problem. If not I can do another test
run, but it might take some time.

Can you build from Subversion trunk and test.  I have a Haicom
SiRF-2 device that seems to work fine.

Still happens for me (Debian squeeze / i386, Debian lenny / amd64) at
6401, but only with --enable-dbus. Will try to reproduce the SiRF-2
protocol loop bug later today.

Still occured at revision 6401. Debug output for various log levels is
at [1-5].

Those are 404 for me.  And my Haicom is fine.

Have you considered running a bisection test with lower bound at 2.37
and upper bound at 6401?  Knowing the revision where your device stopped
working would ptobably pinft the bug down enough for a fix.

My SiRF-2 device still works, so this is quite puzzling.

Fixed (forgot to synch with the external server), but you can forget
about them anyway. Due to environment differences I launched the distro
version (2.39) instead of the svn one. As of revision 6401 it seems to
work fine (i.e. I can't see it cycling anymore). Thanks!
