Status : problem is being debugged
Does this still happen with -rc6?
Unfortunately, yes. I tried rc6, current git, and currrent git + David
Rientjes' patch. They all show the same behaviour.
It's probably another bug in the memmap parsing rewrite (Mel cc'ed)
but the debugging information in the standard kernel unfortunately
doesn't give enough output to find out where it happens.
Feel free to send me a debugging patch..
You should have received such a patch from me later in the thread. In
combination with the patch at http://lkml.org/lkml/2006/11/10/198 and a
copy of the dmesg, I might be able to guess what is going wrong. Thanks
