You didn't hit breakpoints, but signals. You need to do this:
<shell prompt>gdb linux

<gdb prompt> handle SIGSEGV pass nostop noprint
> handle SIGUSR1 pass nostop noprint

for instance:
run ubd0=3D~/Uml/root_fs_toms1.7.205 root=3D/dev/ubd0
type cont if it stops with SIGTRAP

then, it will stop saying "breakpoint hit" and then you can type "bt" and p=
ost=20
the resulting backtrace. But you need a kernel with debugging symbols, whil=
e=20
this is not:
