 I ran into a similar error to this a few days ago (running a 7.0_RC1
 kernel), but the system wasn't under load at the time, it was booting,
 and failed to complete booting because of this. I haven't seen this
 since, though, it's working fine for me now. (I upgraded to 7.0_RC2
 yesterday.)
 
 The dmesg output I have is a bit different:
 
 usmsc0: warning: Failed to write register 0x10c
 usmsc0: warning: Failed to write register 0x110
 usmsc0: warning: Failed to write register 0x100
 usmsc0: warning: Failed to read register 0x130

 [then more repeated output]
