USB Keyboard Strangeness
After finally getting around to updating one of my machines to 2.8,
I was unable to use the keyboard (USB) -
the usb key is on the front panel, the rest is on the back -
I didn't play around with which port is what (but of course
would be glad to do so)
This did not happen on the usb key boot media,
nor when booting from hdd with the usb key in my USB port -
- 2.8 SMP - hdd & usb key
- 2.8 UP - hdd & usb key
- HEAD SMP - hdd only
- HEAD SMP (no acpi) - hdd only
all with the same results.
Related dmesg / usbdevs from hdd acpi smp boots attached -
relavent diff seems to be that the usb key is hooked
into the 'ehci' hub - not sure how this relates
to the multiple ehci/ohci controller stuff in ehci(4) -
and it seems maybe the timing / interrupts get matched
differently depending on the presence of the key -
there's some bit about 'waiting for bios to release control'
of ehci - I'm thinking maybe if I interject a sleep into
this phase of the boot it might help -
happy to hack up my tree if anyone has ideas-
I know this does sound similar to other usb related
strangeness of late.. hmm.
