--- Begin Message ---Package: user-mode-linux Version: 2.6.32-1um-4+48squeeze1 Severity: normal When trying to trace running processes (either strace or gdb), programs freeze. As an example: $ cat test.c #include <stdio.h> int main(void) { fprintf(stdout, "Hello, World!\n"); return 0; } $ gcc -g -o test test.c $ strace ./test gives the following warning: ------------[ cut here ]------------ WARNING: at kernel/sched.c:2628 wake_up_process+0x34/0x40() Modules linked in: ipv6 binfmt_misc 48fa3e94: [<0809c7b0>] warn_slowpath_common+0x60/0x90 48fa3ea4: [<080996d4>] wake_up_process+0x34/0x40 48fa3eb8: [<080996d4>] wake_up_process+0x34/0x40 48fa3ecc: [<080601c5>] arch_ptrace+0x155/0x360 48fa3ee4: [<080af7e7>] find_task_by_pid_ns+0x17/0x40 48fa3eec: [<080a6629>] ptrace_check_attach+0x69/0x90 48fa3f00: [<080a6a3f>] sys_ptrace+0x7f/0x150 48fa3f24: [<08062c0b>] handle_syscall+0xbb/0xc0 48fa3f40: [<080a69c0>] sys_ptrace+0x0/0x150 48fa3f6c: [<080915e2>] userspace+0x3a2/0x560 48fa3fec: [<0805fcad>] fork_handler+0x5d/0x70 ---[ end trace d636ea18fe67c05f ]--- and the process freezes. The same behaviour can be observed when using gdb (this is how I found it). Rolled back to previous version (2.6.32-1um-4+45) and tested the same test program -- the incorrect behaviour is no longer observed. -- System Information: Debian Release: 6.0.7 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: i386 (i686) Kernel: Linux 2.6.32-5-686 (SMP w/2 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages user-mode-linux depends on: ii libc6 2.11.3-4 Embedded GNU C Library: Shared lib ii uml-utilities 20070815-1.1 User-mode Linux (utility programs) user-mode-linux recommends no packages.
