The following reply was made to PR kern/11146; it has been noted by GNATS. From: Andrew Kenneth Milton <akm@zeus.theinternet.com.au> To: bde@zeta.org.au (Bruce Evans) Cc: akm@theinternet.com.au, FreeBSD-gnats-submit@FreeBSD.ORG Subject: Re: kern/11146: 2nd ISA Cyclades-Y not recognised Date: Thu, 15 Apr 1999 16:00:21 +1000 (EST) +----[ Bruce Evans ]--------------------------------------------- | >>Description: | > | > When adding a 2nd ISA cyclades-Y adapter, boot -c shows that the | > devices are conflicting with each other even though they do not | > share IRQs or IO addresses. | | This is a red herring.
