Hi!
I have also the problem with a dlt drive HP C9264CB (with
media changer). After I have discovered, that after a
rmmod st ; modprobe st
the tape is working again, I take same "readings" in the
code of st.c.
I think, I have detect a bug. The st_buf_fragment[] should
begin after the scatterlist[]

*** 3530,3536 ****
tb->use_sg = max_sg;
if (segs > 0)
tb->b_data = page_address(tb->sg[0].page);
! tb->frp = (struct st_buf_fragment *)(&(tb->sg[0]) + max_sg);
tb->in_use = 1;
tb->dma = need_dma;
--- 3530,3536 ----
tb->use_sg = max_sg;
if (segs > 0)
tb->b_data = page_address(tb->sg[0].page);
! tb->frp = (struct st_buf_fragment *)(&(tb->sg[max_sg]));
tb->in_use = 1;
tb->dma = need_dma;
I have it not tested, because the tape drive is in a datacenter
of a provider, and "killing" the kernel will not be repairable
with an ssh-connect ;-( I can't get the tape out off the data-
center before friday..
