   1 Subject: Increase cancel timeout
   2 From: Brian King <brking@linux.vnet.ibm.com>

   5 During cancel testing it has been shown that 15 seconds is not
   6 nearly long enough for the VIOS to respond to a cancel under
   7 loaded situations. Increasing this timeout to 60 seconds allows
   8 time for the VIOS to cancel the outstanding commands and prevents
   9 us from escalating to a full host reset, which can take much longer.
