I can confirm this behaviour on FreeBSD 6.2. It sometimes freezes or panic when I atacontrol detach ataX and then physically remove the disk. (disk is used in gmirror). I saw some panics on reinsertion too. The strange is that it behaves better when disk is removed / reinserted without detaching ata channnel by atacontrol. (tested on Sun Fire X2100) Miroslav Lachman
