No, I don't think there is any known fix for it. However, does this problem
keep on and makes debugging impossible (i.e., after you "cont", does it keep
stopping)?

Hmm, are you doing debugging in SKAS or in TT mode? In the second case, then
it can be a bug in the ptrace proxy (which has a big bug with some gdb
releases >= 6.0).
In the first case, maybe it's something I observed too (I'm not sure because I
don't use a lot gdb with UML)... Better, I've observed breakpoints being
*skipped* by gdb.
