As of Friday's linux-next I've been unable to successfully boot using an nfs root with a c6x board. I bisected it to this patch: commit cc3b296fd9a01c9e654bcb9373af70dd6e32fb24 Author: Trond Myklebust <Trond.Myklebust@xxxxxxxxxx> Date: Thu Jun 21 14:53:10 2012 -0400 SUNRPC: Clean up xdr_read_pages and xdr_enter_page I placed "good-boot" and "bad-boot" packet capture files at: http://people.redhat.com/~msalter/linux-next/ The only difference in the kernels used is the above patch. The bad-boot mounted the nfs root but was unable to find the init file which caused a panic. The nfsroot= parameter uses v3,tcp flags and the server side is running rhel6. I'm not at all familiar with the nfs code, but can help with testing or providing any addtional info needed. --Mark -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
