Subject:   -91- Why is my Indigo2 panicking under IRIX 4.0.5?
Date: 13 Nov 1994 00:00:01 EST

  There are several keyboard-related bugs in IRIX 4.0.5H and 4.0.5IOP
  which cause Indigo2s to crash or freeze. One sign that these
  particular bugs are responsible is the message "PANIC: Timeout Table
  Overflow" or "WARNING: Couldn't allocate streams buffer" in
  /usr/adm/SYSLOG.  Get the "Indigo2 keyboard patch" (aka "pckm patch")
  or upgrade to IRIX 5.2.
