Btw, is the >2.6.12 series ready for production-environments?
If not, which is the last known stable version you can suggest?

I am so far unable to reproduce the corruption with this workaround patch.
So it looks like we have at least one fix.

Hi,
Is it possible to use libusb inside UML to access USB devices?
I see a note on the website regarding a patch for this from 2001,
so I'm assuming it is possible, but I'm having trouble turning
any USB options on in the kernel config.
Any tips appreciated.
Thank

Is this true? Are file capabilities not available in UML?
I'm using a 2.6.35.5 based kernel.

does it sound reasonable that 256MB of memory is in use? if so can
you trim that down?
if this seems too high we need to see if there is a leak somewhere
I'm observing strace(1) behaving oddly under recent 2.4.x
versions. Under 2.4.27 with uml-patch-2.4.27-1 and strace
4.5.8, we get:

execve("/bin/echo", ["/bin/echo"], [/* 13 vars */]) = 0
exit_group(0) = ?
which isn't very useful.
