It sounds like a problem with an underlying driver.
I'm doubt it's worth trying to work around in dd. Besides,
what can dd do? If you request a block size of 32, it can't
very well opt to use 512 because using 32 might make hang a
buggy driver.

Did you try specifying just the *output* block size?
E.g., rather than using bs=32 (which sets both input and output
block sizes), specify only obs=32.
