Hi,
my problem still exists: the UML hangs om hdd-intensive processess (like
apt-get dist-upgrade). I tried a lot of things in time:
o tried on 2 machines with different hardware, different Host- and
Guest-Kernels
o CONFIG_BLK_DEV_UBD_SYNC is not set
o tried ext2/reiserfs on the Guest-UML
o when

Okay, UML repeats its output when the pipe it's writing into fills up
until it returns -EAGAIN. I can reproduce this even on a fast machine
by repeatedly suspending the xterm that UML is running under with a dumb
little script ala:
while /bin/true
do
kill -STOP $PID
sleep 1

No, because the patch is wrong. It should export both symbols in the second
case.

This happened with CONFIG_HIGHMEM enabled on a almost-vanilla 2.6.11... with
that option disabled I don't see such problems (also tested on both the same
exact kernel, and with nearby ones).
To sum up, there is a read() syscall, a copy_to_user() (which calls kmap())
with preemption disabled (in

That's when you set the network links to feed entropy. It may not be

This time, I've announced this on my homepage, since I'd like to get a lot
more testing and to release this patch unchanged as -V8 final version.
Things I've forgot:
* make it apply easily on Fedora kernels.
This should simply mean moving the TIF_SYSCALL_EMU to place no.8, to leave a
slot free

Hi Rob,

I think it is a combination of both: When installing just one single
debian-package the UML often freezes :-(
Is there an alternative to UBD?

which isn't? I would call that a compiler which lies about its
