dlg@ fixed some panics that were caused by removing sd(4) devices not so long ago, e.g. sys/scsi/sd.c r1.212. anyway, this patch doesn't touch umass(4), so it probably isn't a whole lot of help for that particular case. for people testing this, I'm more interested that it doesn't break anything, than that it fixes some particular case, because I already know that it does fix some particular cases. -- jake...@sdf.lonestar.org SDF Public Access UNIX System - http://sdf.lonestar.org
