Hi, all:
Sorry to trouble you again. But I really tried very hard on installing
xen on my machine. I reformatted my whole disk, install Ubuntu 10.04,
and compile Xen and Kernel from the source code.
Ok.. why? Why didn't you just re-build?
it gives out info this time, saying something about
BUG: scheduling while atomic: rsyslogd/565/0x10000001
kernel BUG at arch/x86/mm/highmem_32.c:45!
The .config that Pasi pointed has this:
# CONFIG_HIGHPTE is not set
That is what you need in your .config file.
Why? That shouldn't be necessary, and is disabled at runtime even
if you enable it.
Didn't we have some trouble with this?
We had trouble with it being enabled; my recommendation has been to
leave it off. But now we disable it at runtime by just not allocating
ptes in high memory, so we don't need to deal with them any more.
But I haven't looked at this specific BUG; what's the failure?
