Hello,
I solved the mystery,
I found that the element who triggers the bug ( random hang at boot with
kernel 3.17 and 3.18 ) is the combination of 3 elements :
- the use of a SATA DVD burner ( Liteon iHAS124 C ) on a ICH7 Sata controler
- the use of a gigabyte motherboard GA-P31-DSL3 ( bios F10A

Hi Barto,
sorry for the late reply, and thanks for drilling down the exact
conditions.
I think we have some issues with the lack of the host lock vs error
handling, but I still don't undertand the details.
I've got a test patch for you that just adds the host lock back in a few
places while k
Any chance to get some reviews for this series? I'd like to get it in
for the 3.19 window to avoid two related API changes in two consecutive
releases.
