I got repeatable hang situation, but I can't obtain a kernel dump to get result of all show commands from here: http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneldebug-deadlocks.html After my break to debugger using Ctrl+Alt+Esc sequence and entering a "panic" command kernel does not wrote a kernel dump but seems to hang. Can anyone describe how to obtain a kernel dump in this situation, or at least say - which output of show commands need in first place to debug this ? Output of all suggested commands is huge and I afraid of making mistake when carrying this output from screen to list of paper and back :-) -- Oleg Derevenetz OOD3-RIPE Phone: +7 4732 539880 Fax: +7 4732 531415 http://www.vsi.ru CenterTelecom Voronezh ISP http://isp.vsi.ru
