Dear All, I selected CentOS5 in my works and installed them in two DELL PowerEdge1950. However, a trouble blocked me during the machines run after two days.

[http_cap:12228] ............. ----------------------------------------------------------------------------------- I choose CentOS because I believe it is the most stable OS in commodity machines. But I don't know how to do when facing the trouble. The difference lies in that I patched a PF_RING patch in original kernel and recompiled the kernel to run my machines. I wonder whether the patched kernel crashes the CentOS because PF_RING automatically downloads the kernel codes from www.kernel.org, but not the one from www.centos.org? Or, the centOS holds the bugs in its distribution?
This is very common, a google search for: 'poweredge 1950' 'BUG: soft lockup' 'stuck'produces almost 2000 results. It seems to be something to do with the on board network ports.
I do not seen this problem ... has anyone else?
