thanks. I can reproduce this:

$ stap a.stp 
semantic error: failed to retrieve location attribute for local 'bio'
(dieoffset: 0x1e58415): identifier '$bio' at
/usr/share//systemtap/tapset/ioblock.stp:103:33
        source:         devname = __bio_devname($bio)
                                                ^
semantic error: failed to retrieve location attribute for local 'bio'
(dieoffset: 0x1e58415): identifier '$bio' at :108:14
        source:         rw = $bio->bi_rw
                             ^
semantic error: failed to retrieve location attribute for local 'bio'
(dieoffset: 0x1e58415): identifier '$bio' at :114:16
        source:         size = $bio->bi_size
                               ^
Pass 2: analysis failed.  Try again with another '--vp 01' option.
