So far I have tried the following without success:

- Two harddrives: IBM Travelstar 5G och Quantum Fireball 1G2 (one at a time)
- Devboard_lx-R1_0_0 and R2_0_0
- 5cm and 20cm long cables
- Two boards (I can see the esd-clamps inside Etrax on all pins so there are
no breaks and I couldn't find any short circuits either.)
- Windows and Linux fdisk
- mke2fs with and without "-O none -r 0"
- timing i ide.c: all 5/15/5 and all 31/31/31, also DMA timings
- MAX_HW_IFS 1 in ide.h (to make booting without a hd faster)
- with and without pull-downs at intrqX and dmarqX
- dancing under full moon

>And strange enough why does identify command work but not any other?

Sounds like SW. This is the output I get, very similar:

Uniform Multi-Platform E-IDE driver Revision: 6.31

Partition check:
 hda: (here it hangs up)


It seems to hang up at bread, but why?


if (!(bh = bread(dev,0,get_ptable_blocksize(dev)))) {
  if (warn_no_part) printk(" unable to read partition table\n");
  return -1;

Any help on this would really be appreciated,
