This somehow fell through the cracks. First of all there is no kernel bug per se that I can see, rather a bug in = the atom cpu which started manifesting itself. There were several changes to the affected code path on stable/11 and in particular the condition which trigg= ered the bug is gone. I don't have any reports, but I suspect stable/11 is now cleared. stable/10 will require a hack, but I'll need someone to test it as don't have the hardware to reproduce. --=20 You are receiving this mail because: You are on the CC list for the bug.=
