I recently got a Landisk (HDL-???U model). I've had some issues with the 
PATA controller not detecting the attached disk with 2.6.35.10 so I've 
been trying to get a newer kernel running to see if it makes any 
difference..
All kernels newer than 2.6.35.10 seem to panic just after booting. I 
have appended output of  2.6.38-rc4-next-20110211 but it's the same with 
2.6.37. The kernel config is the default landisk one.
