Calling doadump() seems to work ok, but after a reset there's no dump. I haven't had time to test this systematically.

Minidumps in -STABLE and "smaller than physical memory"
Hello! I've noticed (with the 2-day old RELENG_6) that I still can't configure my 256Mb swap partition as a dump device for i386 machine with 1Gb RAM despite having minidumps enabled: [EMAIL PROTECTED] sysctl debug.minidump debug.minidump: 1 [EMAIL PROTECTED] dumpon -v /dev/ad0s3b /dev/ad0s3b is smaller than physical memory Am I correctly understand that minidumps should lift the restriction sizeof(dumpdev) >= sizeof(RAM) ?
