One trick that you might do maybe try running opcontrol with the following to find out what commands are being run: > > sh -x /usr/bin/opcontrol --start >& opcontrol.log > > The ouptput in opcontrol.log might give a better idea where the write error occurred. > Hi William, Thanks for your reply. The output in opcontrol.log looks like this: ... + test yes = yes -a -f /dev/oprofile/backtrace_depth + set_param backtrace_depth 0 + test yes = yes + echo 0 sh: write error: Invalid argument I put the entire opcontrol.log here: http://tny.cz/b3a27478. > > Is opjitconv built and installed?

It's a bit space-constricted, so I couldn't put all the binaries on there. Currently, my directory looks like this: # pwd /root # ls mips opcontrol.log opreport op-check-perfevents ophelp oprofiled opcontrol opjitconv The 'mips' directory contains one folder, '74K', which I copied from my $PREFIX/share/oprofile/mips directory after it had finished compiling.
