Christopher, no, I can't upgrade the BIOS; my wifi card its not Lenovo
branded, and I had to hack the whitelist in the BIOS to use the card at
all. In any case, this is an issue with the wifi card itself, so
unrelated to the system BIOS.

But the problem has not recurred with more recent kernel releases, so
closing as resolved.

Title:
  8086:422b [Lenovo ThinkPad ThinkPad X201] unreliability with Centrino
  Ultimate-N 6300 wireless connection, 802.11n

Status in “linux” package in Ubuntu:
  Fix Released

Bug description:
  My laptop has been experiencing occasional drops from the 802.11n
  wireless with the current kernel.  When this happens, the card cannot
  see any ESSIDs and spews the error "Request scan called when driver
  not ready."  If I try to unload and reload the module, I get an
  "unable to init EEPROM" error.

  Kernel log snippet follows below.  The modprobe -r/modprobe happens at 13:25:39.  Rebooting clears the error:
