after a little modification (which made a difference even though it
shouldn't have), I have been able to get output from part_blk. Now, I have
narrowed the problem down to the following bit of code:
Sector(unsigned long blk_nr,
unsigned long count,
bool write = false)
: _session(Driver::driver().session()),
_p(_session.dma_alloc_packet(Driver::driver().blk_size()
* count),
write ? Packet_descriptor::WRITE :
Packet_descriptor::READ,
blk_nr, count)
Somewhere in there, it freezes. If I had more time, I would break it up and
dig deeper.
