People who care do not always have the resources to make regular tests with their hardware. I for once have meant to check the original series against my 486 EISA box since Ingo posted them back in May last year, and I still have them stashed away for this purpose. Unfortunately I didn't get to wire that machine for remote console access and power supply control (and I have since run out of ports too), so I need to physically get to its location to do any testing. So it's not unusual for bugs in the less common configurations to only surface a bit later on, as people get to making an upgrade. At least we have `git bisect' available and individual changes recorded now, which makes tracking down regressions a lot easier than it used to be in the old days. Maciej
