This and a few other things are documented there. If you get many _repeated_ SIGTRAP under GDB, that's another problem, but I found a workaround which worked on anything I tested (starting from 2.6.13-bs). > Is the UML generating trap signals? > If so, is there a way not to generate them, or tell gdb to ignore them? > > *) pass mode=tt.

Then the problem is in SKAS0 mode - it's a relatively new feature and there are some environments on which it doesn't work. > > *) Try using a different UML version - there is my -bs tree, on my > > homepage (see signature), which is more up-to-date than -stable kernels > > (applies on them though).
