I'm not intending to swamp this list, but I'd like to share some
additional information about this hanging issue. At the time when UML
hangs, there are four threads running in it.
Below, I'm providing their stack traces as shown by gdb:

Hi Godmar,
I had the same symptom last week. It isn't always related to VDSO:

That patch resolved my issue, but I don't want to send you barking up
the wrong tree. This specific issue is supposed to be resolved by

Scott,
2.6.22.5 appears to already contain this patch. FWIW, here is the
startup output:
Checking that ptrace can change system call numbers...OK
Checking syscall emulation patch for ptrace...OK
Checking advanced syscall emulation patch for ptrace...OK
Checking for tmpfs mount on /dev/shm...OK

Hey Godmar,
When I was experiencing the hang, I'd still get the output you list
below. I wasn't saying that the patch was your answer, just that it's
not necessarily the VDSO issue. In my experience, the issue disappeared
when I used the 2.6.21.5 guest kernel instead of a 2.6.14 guest kernel
on RH
When building a UML kernel based on 2.6.22.5, I seeing warnings such
as this one:
MODPOST vmlinux

to .init.text: (between 'kthreadd' and 'init_waitqueue_head')

What do these warnings indicate? It appears to be s

Hi all,
I’d use UML to emulate wireless LAN and mesh scenarios. In particular,
I’m interested in emulating links with different SNR hidden nodes and
using iwconfig/iwlist tools on VMs to analyze network status.
First of all, I’ll work with fixed nodes only, then, the next step will
be mobile n
Oops! I meant to send this to the list and would up only replying to Andrea
directly.
