Yes, current 2.6.22.1-rt4 is still locking-up on my ix86 SMT/SMP boxes. I'll have to wait for some hours of uptime and normal desktop use and then it just locks-up without warning. Last couple of occurrences were all while browsing with firefox (2.0.0.5) or using openoffice.org (2.0.4) but in rare and non-deterministic fashion I must say. It looks very similar to the previous ones I've reported before for -rt3, but I am no expert in these things. ...
