There are now 2 probes, 1`for floppy hardware done where the fdc0 messages are and 1 done for floppy media by GEOM, right at the end of boot (while discovering disks). If the first one gets the config wrong, the second triggers the hang. This was previously hidden by the fact that in the past, we didn't bother with media in the drive during boot, only when someone made a mount or read attempt from /dev/fd0 at runtime. The fix is to get the config right. At the moment, I believe both RELENG_5 and -current take into account all known settings. It's quite possible there are other config issues, possibly triggered by nonstandard hardware (i.e., media line change), that we'll have to account for. -- NateReceived on Thu Sep 30 2004 - 14:28:37 UTC
