However, there is still a less frequent problem with ptrace (which also
occurred even when I'd applied my workaround patch). When running
firefox under gdb only, display corruption and odd crashes in
floating-point code are seen - which are the same symptoms as I had
before.
So I assume that something is still wrong with the floating-point
save/restore in the case where a process is being ptraced.
Does this bug still exhibit if you add in your patch to always set
CR0_TS on task switch?
