I'm not too surprised. Non-PAE Xen is a bit of a rarity, and it only
gets tested rarely. Chris Wright did spend some time on it a while ago,
but I don't know that its had any real attention since. I've been
making sure non-PAE compiles, but I've been lax about testing it.
This is the first usermode exec, I guess? The backtrace is a bit odd;
I've never seen a problem in move_page_tables before.
Yes its trying to execute the first script in initramfs, I also tried with
initramdisk
and got a similar error. (move_page_tables also involved)
Does "xm dmesg" tell you what Xen is complaining about? You may need to
compile with debug=y in Config.mk.
(XEN) mm.c:645:d44 Non-privileged (44) attempt to map I/O space 00000000
I will recompile with debug=y and post the output.
If I reduce the dom0 memory with dom0_mem=200000 I see something like
00000080 with dom0_mem=800000 I always see 00000000.
That's helpful. Looks like the mfn is getting mushed to 0.
