As I noted I was pretty sure that there already were PR's for this (since this issue really comes up every few weeks on the mailing lists). Anyway I just quickly checked and other PR's which deal with the same basic problem (which is that bad thing happens if devices disappear under a mounted file system): 72119 freebsd- kern open serious medium current-us Detachin= g USB Memory Stick w/o umount causes zombie devfs node 30160 freebsd- kern feedback serious medium current-us [panic] = kernel panic when flash disk is removed and the flash disk is mounted. 40787 freebsd- kern open serious low current-us kernel p= anic if PCMCIA CD-drive with mounted medium is removed So I don't see the need to keep this PR open. --=20 Simon L.
