[coLinux-devel] 0.5.4: i686-optimized vmlinux along with i686-optimized userspace - segfaults

[Dan A. <da...@co...>]

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.
