i686-optimized userspace - segfaults


| Hello,
|
| I've figured the issue mentioned in the topic. Well, apparently the
optimized
| kernel code corrupts MMX / FPU registers for userspace while in the path
| between hardware interrupt handling and forwarding to the host.
|
| It occurs more often when the coLinux machine gets more CPU from the host,
| since hardware interrupts are caught more often in that situation.
|
| A i386-compatible vmlinux gets around it, but it's not the solution I
want.
|
| I'm now working on a fix, while also merging Ballard's patches.

Does the latest snapshot (20040305) fix the seg fault issues?
