It's just impossible to fix them without having a bounce buffer. The only way would be to not use the hardware. I guess we can find out how many people still use floppies and other such hardware by having it for some time in -mm*. But I reserve the right that if this thing becomes a FAQ - e.g. various people set the option wrong and break their systems to rip it out again. I'm not interested at all in patches that increase the bogus bug report rate. -Andi
