Hi Maria,
I had something similar with vanilla 2.6.37 just for running:
cscope -R -b -q
allways hang complety the process, only solution reboot.
I just applied the btrfs patches that arrived in the main tree between=
the=20
2.6.37 and 2.6.38-rc1 and they seem to fix the issue.
I did not have the time to try to found which patch fixed the problem.
Hope this could help you.
Cheers,
//Rui
