Both rc6 and rc7 has a different problem - the machine tends to hang after some minutes work in X. That hang is unusual in that moving the mouse still move the X cursor, but everything else stops and sysrq fails me. But that is another story. rc6 boots, rc6-mm1 hangs at the "usbcore registered hiddev" message. Bisection: 1, 2, 3: the three first hangs at "usbcore registered hiddev" 4, 5, 6: the next three hangs at a message about ACPI PCI[A]->IRQ17 I decided to keep bisecting these hangers as "bad", I don't really know if this could be the same thing or completely different issues. If they are different, then one problem will mask the other anyway, so calling every hanging kernel "bad" will at least find the first broken patch. 7: boots up ok! 8,9,10: hangs at the aboce mentioned ACPI message The (first) "hanging" patch in 2.6.21-rc6-mm1 is: git-acpi.patch Helge Hafting
