Quite, and there was also a bisection on the clk-next branch.  If
some subsystem branches don't rebase with the fix and the problem
keeps happening then we'll be disabling boot bisections for them
temporarily to avoid email noise.

On a side note, we're also planning to add a way to mark a
revision as fixed to stop reporting particular failures that have
been fixed upstream - but that's not possible at the moment.

Great, thanks!  Sorry I missed that thread.  Thank you also for
having mentioned the kernelci.org bot in the fix.
