The system is usually able to stay up for a day before the hang. But it is quite consistent in that it always hangs. I experienced the same hang with 2.6.5-bk1 as well. In the thread traces, it looks as though the mmap_sem of pid 3960 (pan) is not being released preventing any other process from locking the address space. This is readily apparent from the hung "ps" command. It is trying to read "/proc/3960/stat". Any clues would be appreciated as I have not been able to make any headway in debugging this. My hardware information is below and I have attached the sysrq-t output and .config. Thanks, Shantanu Kernel version: 2.6.6-rc1 SMP Hardware Info: Dell PE1600SC with 2x2Ghz Xeon CPUs D __________________________________ Do you Yahoo!? Yahoo!
