Tested a bit more and the problem doesn't seem to be PMP support itself.
 Command issue doesn't work properly if follow up SRST is issued without
clearing SError after issuing hardreset.  2.6.26 always clears SError
after hardreset so it should work.  Piter, can you please remove SIS
blacklist and test 2.6.26?

Thanks.
