 his problem occurs only when using "gamer" usb keyboards that have  more
 than 50 variable keys
 on cheap chinese or not programable keyboards, that have few keys, it does
 not occurs
 
 Also, when a "gamer" type usb is connect it includes several ukbd at once:
 
 [ 2.694665] uhidev0: SEMICO (0x1a2c) USB gaming keyboard KX410TKL (0x44c8),
 rev 1.10/1.10, addr 2, iclass 3/1
 [ 2.704665] ukbd0 at uhidev0: 8 Variable keys, 6 Array codes   <<< seems OK
 [ 2.704665] uhidev1: SEMICO (0x1a2c) USB gaming keyboard KX410TKL (0x44c8),
 rev 1.10/1.10, addr 2, iclass 3/1
 [ 2.724665] ukbd1: autoconfiguration error: attach failed, key code size !=
 8
 
 the cpu runs fine but if the keyboard disconnect ... the system panics on
 ukbd detach,
 
 Crash version 10.0_BETA, image version 10.0_BETA.

 ============================================
 as one can see the ukbd struct data is corrupt probably when read
 descripton from the keyboard
 
 Hope it can help
