Unfortunately the patch applied to 2.6.27.13 didn't change anything, still hanging - see below. Full output is available at the web. Adding mem=512k hung also with a 2.6.28 series kernel. Any further ideas ?

Yes, I didn't expect that to help. I'm real busy but will get back to you with some new debugging patches hopefully in the next few days. -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
