Thanks for the suggestion Stephen, but it didn't make any difference.
I've been doing some more digging around and I believe the problem was
introduced
in 2.6.13-rc1. 2.6.12{,.1,.2,.3,.4,.5,.6} all work fine but I get the keyboard
lock-up
with 2.6.13-rc1. I've also come across another symptom. Occasionally, a
keypress will repeat as if the key is being held down. The only way to stop it
is to unplug the keyboard. As before.once the keyboard is plugged in again, it
works without problem.
I've also got some more diagnostics by "enabling" some code that was previously
guarded by an #ifdef 0/#endif pair. An extract from /var/log/debug is attached.
The USB error message that I mentioned in my original post is at line 329 of
this
log, but is now accompanied by additional diagnostics. Does this mean anything
to anyone, please? The error is immediately preceded by something about Babble
and something being Stalled.
I've also backed out one or two at a time, all the uhci related patches (plus
any
dependent patches to host or core) that went into -rc1 but that hasn't made any
difference. Bearing in mind the new diagnostics, does anyone have a suggestion
about where I should look next, please?
Thanks
