[Mono-devel-list] Mono segfaults with updated kernel?? 2.6.10

[Zoltan Varga]

                                  Hi,

  Are you by any chance using a kernel with Ingo Molnar's ExecShield
patch ? Mono is
known to not work with that patch. This will be fixed in the next
release. AFAIK,
whenever a kernel uses ExecShield can be detected by the existence of
 /proc/sys/kernel/exec-shield 

                   Zoltan
