If the disk has an unreadable spot, it is possible to crash the running system. Crashing the system in multi-user mode is more of a problem than doing it in single user mode. But, the point remains that a dump/restore in multi-user mode is doable. ////jerry > > ////jerry > > > > > -----Original Message----- > > From: Jerry McAllister [mailto:jerrymc@clunix.cl.msu.edu] > > Sent: 05 November 2002 19:44 > > To: neil@mpfreescene.com > > Cc: freebsd-questions@FreeBSD.ORG > > Subject: Re: Kernal Panics > > > > > > > > Hi, ive been getting kernel panics, number 12's for some time, ive had > > > the whole load of hardware changed, the only thing that is the same > > now > > > is the hard disk drive. > > > > > > We thought this had cured the problem, but I had one the other day. > > > Okay, I thought this was a one off, but I just had another, only this > > > time it is different.
