<html><body><div style="color:#000; background-color:#fff; font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, Sans-Serif;font-size:16px"><div class="" style="">Thanks for your reply. The screen freezes for about 5 seconds, then the errors show up. I tried running "<span style="color: rgb(46, 26, 5); font-family: monospace; font-size: 13px;" class="">echo -n 0 > /sys/module/i915/parameters/enable_hangcheck" before executing "pyrit selfcheck", but that freezes the screen until reboot (I waited about 10 minutes). So it looks like it must be a different issue.</span></div> <div class="qtdSeparateBR"><br><br></div><div class="yahoo_quoted" style="display: block;"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, Sans-Serif; font-size: 16px;" class=""> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, Sans-Serif; font-size: 16px;" class=""> <div dir="ltr"
