[User-mode-linux-user] problems executing uml-2.3.99-pre8
|

First of all thanks Jeff for your reply
The problem about missing "asm/arch/*.h" was becuase I was trying to build
the kernel with "make vmlinux", building it with "make linux" worked Ok...
but I still have some problems, I hope this time I include enough info
arch = i386
host kernel = 2.2.99-pre98 & 2.2.15
uml kernel = 2.2.99-pre98
when I execute "./linux" it keeps heating nearly all CPU, there is no printk
output at all
I include all strace output but first take a look at last few lines:

^^^^^^ Please note the these arguments... is it correct?
<-- Here I press Control-C
862 --- SIGINT (Interrupt) ---
862 +++ killed by SIGINT +++
what it's happening here?
I've tried with several kernel with diferent config options (devfs on/on and
debugging on/off), with host kernel 2.2.15 and 2.3.99-pre8
I also tried running it by passing ubd0=root_fs, but as I said before __it
doesn't show any printk__
Thanks in advance
