Today though it seems i was lucky and actually managed to catch a kernel panic while in console mode. Below is the actual panic message, i tried looking at the actual backtrace but all the interesting frames are purely addresses without any symbol information. I'll assume this is because of zfs and friends being loaded as KLDs. Any information on how to provide a proper backtrace including all symbols involved would be appreciated. uname -a: FreeBSD trinity.zion 7.0-CURRENT FreeBSD 7.0-CURRENT #29: Sun Aug 26 20:19:12 CEST 2007 pascal@trinity.zion:/usr/obj/usr/src/sys/TRINITY i386 panic: ZFS: I/O failure (write on off 0: zio 0xc66a9cf0 [L0 ZFS plain file] 20000L/20000P DVA[0]=<0:a126e0000:20000> fletcher2 uncompressed LE contiguous birth=7004722 fill=1 cksum=2dc0c354bd8ccc27:85745b74c1352a7f:72188a8646f7f624:28d89f21264ed4f2): e^ cpuid = 0 KDB: enter: panic panic: from debugger cpuid = 0 Uptime: 13h56m31s Physical memory: 2027 MB Dumping 292 MB: 277 261 245 229 213 197 181 165 149 133 117 101 85 69 53 37 21 5 -- Pascal Hofstee
