I am new to the list, I'm sorry if this has been reported. I get hangs on an amd64 SMP machine, the console prints message about recursive locking and the machine never recovers. I looked for existing bugs but it seems your bug database on sourceforge is empty.
I am using libpfm-3.2-060621.tar.gz pfmon-3.2-060621.tar.gz perfmon-new-base-060621.tar.gz on linux-2.6.17.7.tar.bz2 (kernel.org). I get the hangs when remote attaching to the same process from a script several times. It hangs after about 4-10 such attempts, and did so three times in a row. The process is a big (about 3 GB VM) 32 bit process on FC3/amd64, perfmon2 is compiled as 64 bits. It works fine as far as it goes but then locks up the kernel. Recompiling the kernel without SMP got me the statistics I want without problems. Hardware: 2x Opteron 250 in Tyan Thunder K8W. Has this been reported before?
