Hi,

I've been trying out the kdb, kgdb integration on 2.6.35-rc3, and so far, kdb is useable but kgdb not.

I have a slightly messy configuration, with virtualbox vm, host pipes, and a tcp pipe connector so that one vm monitors the other.  However, I seem to have no trouble using kdb at 115200.  When I try to use kgdb (and I also rebuilt the kernel with only kgdb enabled), gdb hangs, faults, etc.  The initial reported error is "warning: unrecognized item "timeout" in "qSupported" response."

I'm guessing the problem could be the gdb--I'm using fedora 13's 7.1-26.  Can anyone make suggestions?

Matt
