On my system, pnpinfo reports as follows. # pnpinfo | grep Device Device Description: Creative SB AWE64 PnP Logical Device ID: CTL0042 0x42008c0e #0 Device Description: Audio Logical Device ID: CTL7002 0x02708c0e #1 Compatible Device ID: PNPb02f (2fb0d041) Device Description: Game Logical Device ID: CTL0022 0x22008c0e #2 Device Description: WaveTable Logical Device ID: CTL2011 0x11208c0e #3 Compatible Device ID: PNP0600 (0006d041) Device Description: IDE >How-To-Repeat: >Fix: In line 39, isa/pnpparse.c has a constant named MAXDEP, which is set to 8 now. Simply changing the value from 8 to 16 like - #define MAXDEP 8 + #define MAXDEP 16 the message has disappeared. I hope the value is independent of other parts, and a more preferable value is set in the future releases. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
