I have back checked the ide-driver parts that are pre-me and post-me, that is 2.1.121 and 2.1.122. In both cases using an offboard IDE controller (Promise Ultra/33) and calling tape commands via generic 'tar' commands "tar cvvf /dev/ht0".
Everything seems functional under SMP.......at 2.1.123/124/125 there appears to be a hang and DSC timeout. I am hunting through the changes in the driver after 2.1.122 and deeper SMP/IO-APIC changes. If there is nothing in the ide-driver updates in 2.1.123/124/125/126 that 2.1.122 can not handle and ide-2.1.125/126 runs in 2.1.122, then I am left to conclude it is out side. Since there are reports that UP ide-tape is functional and behaving (not verified personally), there may be bigger issues to follow-up.
I recall that there are some new ADAPTEC SMP problems that have popped up lately. These may be totally unrelated issues, but if they are having timing faults also, there may be a crossover effect.
