The following reply was made to PR kern/12495; it has been noted by GNATS. From: "Justin T. Gibbs" <gibbs@caspian.plutotech.com> To: Wilko Bulte <wilko@yedi.iaf.nl> Cc: ken@plutotech.com (Kenneth D.

All CAM device instances 'exist' before the boot up is allowed to progress. If you attempt to open the device while it is initializing, you will block in open until the initialization is complete, but the open will eventually succeed (assuming we were successful in our attempts to initialize the device). The same probing mechanism (parallel probing) is used to find our root device, and I have not heard of an instance where that has failed. I would not expect sysintall to see the world any differently than the mount root code. Perhaps there is another bug in the ahb driver... -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
