Sorry, need to look further. I replaced ehci-pci from 2.6.31.14, and

Do you mean that you took the source code for ehci-hcd from the 2.6.31
kernel, copied it into the source directory for the 2.6.32 kernel, and
built it there?
Exactly that, yes. Two minor patches were necessary in ehci-hcd, but I
doubt that this is the source of the problem (just one administration
structure was pulled out in 2.6.32).
but that required two minor changes because in 2.6.32, apparently, one
hardware related structure was pulled out of the ehci structure.
Still did not make any difference, still locks up.
What's the next module up in the call chain I should be looking at?
Have you tried comparing a usbmon trace from 2.6.31 with a comparable
trace from 2.6.32? I doubt there will be any important differences,
but you never know until you try.
Not yet, good idea, thanks.
Thanks,
Thomas
