This is a multi-part message in MIME format. ------=_NextPart_000_012A_01C05A2D.5FEDC4E0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Howdy, Get the attached panic repeatedly when doing an rm -rf /usr/ports and trying to create a snapshot of the root partition. Sometimes I get the panic when there's no apparent disk activity and trying to create a snapshot on >2GB filesystems. I've included gdb output, dmesg and my kernel config. Hopefully, some-one can make more sense of it in a shorter timeframe than me. If any further information is required, please let me know and I'll try my best to get it to you. BTW, is there any reason I had to enter panic twice in ddb to get the sucker to dump core?
