I bet that it is a kernel issue. What kernel were you running when you saw the mutex issues? I have been running Debian kernel 3.1.1-1 (well, with a small tweak so that I could get it built) with an up to date unstable installation on the ES45 for a week. It is proving quite unreliable. While building git with -j4 on the make, the system fell over in the git test suite. First one CPU froze and became unresponsive, then later the oom-killer was invoked and it all fell over. The freezes of a CPU are still occuring, quite often with file I/O or trying to dismount a partition/disc. I have just downgraded the kernel to 2.6.32 from the Lenny backports distro (plus patches to get the missing syscalls, and other fixes --- the same as what we are running on the buildds) and have not seen a problem. Git test suite passed and have built a couple more packages without problem. I had also noted a couple of more months ago that building eglibc was successful under kernel 2.6.38 but fails the mutex tests in the test suite under kernel 2.6.39 or newer. I intend to report this to the linux-kernel email list in the near future once I have a bit more evidence.
