<p><a class="user-mention" data-hovercard-type="user" data-hovercard-url="/users/JamesWangAmiTw/hovercard" data-octo-click="hovercard-link-click" data-octo-dimensions="link_type:self" href="https://github.com/JamesWangAmiTw">@JamesWangAmiTw</a> The timer callback function is <code>efi_tick()</code>, not <code>efi_currticks()</code>.  The timer event controlled by <code>efi_tick_startup()</code>/<code>efi_tick_shutdown()</code> does not execute the code in <code>efi_currticks()</code>.</p>
<p>There should not be any code path that leads to <code>efi_currticks()</code> while at TPL_APPLICATION.  If such a code path exists, then that code path is missing a call to RaiseTPL.  This is the bug that we need to find and fix.</p>
<p>The most promising approach seems to be for me to reproduce the issue locally.  The tests that I have done so far do not reproduce the issue: I am observing only the expected TPL at all times.  I am working on attempting to reproduce the problem as per <a class="user-mention" data-hovercard-type="user" data-hovercard-url="/users/jjohnson42/hovercard" data-octo-click="hovercard-link-click" data-octo-dimensions="link_type:self" href="https://github.com/jjohnson42">@jjohnson42</a>'s suggestion.  If you have an alternative test case that allows me to reproduce the issue locally then I am happy to use that instead.</p>
