the following patch was just integrated into master: commit 8c20399a42a6bb76f537042b4d7ba725ac78f10c Author: Aaron Durbin adurbin@chromium.org Date: Thu Jan 17 11:13:46 2013 -0600
haswell: wait 10ms after INIT IPI
There should be a fixed 10ms wait after sending an INIT IPI. The previous implementation was just waiting up to 10ms for the IPI to complete the send. That is not correct. The 10ms is unconditional according to the documentation. No ill effects were observed with the previous behavior, but it's important to follow the documentation.
