Can you get the log with a working kernel (2.6.27?) and '#define DEBUG 1' in st.c? Then we could see what are different with the same commands. > I tried again with 'mt setblk 524288', but the > same result: EIO followed by BUG. The corresponding console log is attached as > st-debug-2.6.30.3-mtblk512k.txt. Looks like that the kernel crashes in both logs right after dio transfer? What happens with the kernel module parameter 'try_rdio = 0 try_wdio=0'?
