Dear all,
I had forgotten my motherboard Intel EHCI/UHCI device because up to 2.6.6 vanilla
I would receive hard lock-ups the moment anything was plugged in (e.g. Knoppix 2004_05_17
almost exactly vanilla kernel); I was using an NEC PCI add-in card instead.
However with recent 2.6.7-bk and 2.6.8-rcN the hard lock-ups have gone (I'm using
one of Arjan's rawhide kernels 2.6.7-1.492smp and home-brewed stuff).
Just curious to understand what magic did you folks perform.
Cheers Richard
