Otherwise ktrace doesn't follow fork(2)s beyond the first. In this example, you see at the end: > root:/root# kdump > 18744 ktrace RET ktrace 0 ... > 18744 mount RET stat 0 > 18744 mount CALL fork > 18744 mount RET fork 18745/0x4939 > 18744 mount CALL wait4(0x4939,0xefbfcb5c,0,0) > 18744 mount RET wait4 18745/0x4939 > 18744 mount CALL exit(0x1) This fork was followed by an execve of mount_cd9660, which is what we really wanted to see. Sorry I can't help with the problem. Did you have any other messages in the log files? Greg
