These are a Non-Regression tests done on kernel 2.6.14-rc1. The tests consist in runnning fsx and fsstress. Machines are:
- 2x PPC64 machines, 1Go ram
- 2x IA32 machines, 2Go ram
- 2x x86_64 machines 2Go ram

Test conclusion
There are several problems on the core network functions. These problems do not look nfsv4-specific. However, it is not possible to complete standard Non-Regression tests without crashing the kernel. Here are reproduced the stacks showed by kdb:
