can you get this to happen in single user mode?

I tracked it a little in an earlier version of DEVFS/SLICE: I can't make it happen here. does it still happen to you now and are you using wd or sd? > > I don't know how things are supposed to work but > it seems that msdos_unmount is calling wdsclose via VOP_CLOSE, > setting the du->dk_state to CLOSE. > Later an ffs_unmout is done, which tries an operation on > the now closed disk and panics. THEORETICALLY du (ah you must be usinf wd) should only be modified by the LAST close, but you've given me something to look at. > > I am mounting msdos on wd1s1 > and ufs on wd1s2a,e,f,g. I use sd0s1 an sd0s2a and it all works.. I'll go look at the wd driver and slice_base.c some more. > > > Jonathan Hanna <pangolin@rogers.wave.ca> > > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-current" in the body of the message > To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
