Hi UML people
I'm trying to run a uml kernel v 2.6.17.1 on my laptop.
The same kernel is working perfectly well on 2.6.12 host machine.
My laptop is a 2.6.16-2 machine.
When I turn SKAS mode on the kernel fails:
mapping mmap stub failed, errno = 12
Kernel panic - not syncing: start_userspace : expected SIGSTOP, got status =
256

Yet it works perfectly well on my other (2.6.12) machine.
I tried turning SKAS off and just having TT but that doesn't even
compile:
arch/um/sys-i386/built-in.o: In function `__setup_host_supports_tls':
arch/um/sys-i386/tls.c:366: undefined reference to `check_host_supports_tls'
collect2: ld returned 1 exit status
KSYM .tmp_kallsyms1.S
nm: '.tmp_vmlinux1': No such file
No valid symbol.
make: *** [.tmp_kallsyms1.S] Error 1
Can anyone give me a clue?
