>Good debugging, but the fix is incorrect (or at least unnecessarily slow).
Of course. I posted the working fix (that looked sane to me) because it
was late I had the train pending. I was going to discover _which_ syscall
was clobbering %ebx now, one second before to read your solution ;-).

ret_from_fork:
GET_CURRENT(%ebx)
#ifdef __SMP__
I have not yet rebooted but it' s sure right because the stall was caused
by the new forked processes a bit before return in userspace (infact this
morning I just verifyed that the asm of sys_fork() was saving %ebx right).
If there will be problems I' ll let you know...
