           Summary: GDB 7.2 breaks compatibility from GDB 6.8 with KGDB
           Product: gdb
           Version: 7.2
            Status: NEW
          Severity: normal
          Priority: P2
         Component: remote
        AssignedTo: unassigned@sourceware.org
        ReportedBy: emmanuel.thierry@kerlabs.com


I use GDB to remotely debug a 2.6.30 linux kernel with KGDB.
When I try to connect to KGDB with a 7.2 version of GDB, packaged by ubuntu, I
get a : "trace API error : 0x2". When I use a 6.8 version, packaged by debian,
I have no problem.

This problem happens on connection, just after having typed "target remote $IP"
or "target remote $DEVICE". It happens either with KGDB over ethernet (kgdboe
driver) and over console (kgdboc embedded driver).

Best regards
