2.6.22-1-mepis-smp Quite stable. Have oops sometime inside evdev. Support up to 16 USB keyboards, where 4 hubs are plugged into PC and 4 keyboards on each hub. Any hub cascade support only 4 keyboards, where 5th or more is registered but don't send input events. Oops inside evdev , when USB keyboard unplugged. No slow down even all USB keyboards does not work properly. My be this one support more than 16 keyboards, but i don't have PC USB ports enough.Has the evdev oops been reported and/or fixed? I think that we would prefer to fix that soonish.We haven't seen the respective oops yet, or have I missed it? I'd bet it is fixed in newer kernels by patches that introduce proper locking into evdev code.
If evdev (or any other part of the input sybsystem) still oopses in 2.6.26 and 2.6.27 I would like to see that oops very much. -- Dmitry ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/
