Hi,
I finally found the piece of code that prevents me from booting Xen DomU
with vallina kernel > 2.6.23.1.
The problem is that with every kernel (> 2.6.32.1 including 2.6.24 RCs)
will just hang with "too much" console activity. Sometimes (well most
of the time) boot msg is too much. When I can boot into the kernel,
generating a lots of cosole out it will hang, no oops, no more
console/network. Generating with the same way through ssh will not
hang the domU.
When I reverse the following patch, things work as before, tried this
with 2.6.23.14 and 2.6.14-rc8. But I don't have the knowledge to
understand the reason behind this.
BTW, I am not subscribed.
