This is certainly a bug, but some things about what you've written make me believe that its not quite acurate. Its really important that the messages be correct for me to figure out what is going wrong. Can you try one more time? Any chance you have a second computer that could be on the receiving end of a serial console to record the output verbatum? Also, your 4.3-BETA kernel seems to work okay. Can you give me the revision ids on all of the files in sys/dev/aic7xxx that were used to generate that kernel? Any chance you could step through the commits on the -stable branch from that date forward to see which ones broke the driver for you? The three subsequent commits are: revision 1.94.2.13 date: 2001/03/21 05:00:00; author: gibbs; state: Exp; lines: +7 -8 MFC rev 1.115. Don't allow our DMA engine to be re-enabled late in the shutdown phase of a data transfer by the idle loop fetching an S/G segment. Approved by: jkh ---------------------------- revision 1.94.2.12 date: 2001/03/19 15:09:26; author: gibbs; state: Exp; lines: +4 -3 MFC: Fix phase table lookup and PCI 2.1 retry bug workaround. Approved by: jkh ---------------------------- revision 1.94.2.11 date: 2001/03/12 14:57:43; author: gibbs; state: Exp; lines: +101 -70 MFC: Update to top of tree. You can feed the dates into cvs via the -D option to sync to particular points. Be sure to add 10 minutes to these dates to account for time stamp squew during the commit. -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
