Yes, it wotks very well in most ocations. Your problem seems to be, that you are
trying to import ERDAS 7.4 files, while GRASS still reads them as ERDAS 7.3
format. As ERDAS has changed header format between this versions, this gives
some integer/real number mismatch.

So, try to convert your files back to version 7.3 (ERDAS provides this in 7.4, abd
we haven't got 7.5 yet), and import to GRASS should work. Only problem left is,
when you try to import packed 4-bit files with unequal number of samples.  

Be careful when converting from 7.4 to 7.3, as ERDAS may corrupt your image/map.
, as it writes into the existing header.
it is advisible to make a copy of the image/map first, using ERDAS program
SUBSET.
