And here is the fix: http://www.uwsg.indiana.edu/hypermail/linux/kernel/0405.0/1242.html It is SMP-unsafe though, so in case you have an SMP box with preemption enabled, you'd better wait till the next kernel -pre release: http://www.uwsg.indiana.edu/hypermail/linux/kernel/0405.0/1265.html Or you can use the attached patch instead, which does exactly what Linus said. But I haven't tested that one due to a lack of an SMP box handy. The problem is that noone yet have audithed the 2.6 kernel for dosemu-compatibility the way it was done with 2.4. So using 2.6 with dosemu is not recommended yet, but I already started that work.
