Well, this problem was described earlier - and it's workarounded by exporting the env. var LD_ASSUME_KERNEL=2.4.1 before running UML (so that ld.so will link it against libs in /lib, not in /lib/tls, which contains the NPTL version). It's a bug in the NPTL glibc, which has been later fixed in glibc (I've no confirms of this apart from Ulrich Drepper) and has been workarounded inside UML. > However, I found no discussion of SIGSTOP, except for a race condition > involving PTRACE_STOP which (I hope) was not involved here. -- Paolo Giarrusso, aka Blaisorblade Linux registered user n. 292729 http://www.user-mode-linux.org/~blaisorblade ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
