After a while a timeout message appears with no error bits set (status 50: ready, done). At this point the system freezes up and accepts no input. It is not possible to enter ddb. >How-To-Repeat: It's not clear how specific this problem is to the specific hardware. There appear to be no problems with the primary controller, which may relate to the fact that it services only one disk. >Fix: This bug is specifically DMA related. Disabling the DMA probe allows it to work properly. As such, it could be related to this commit to sys/i386/isa/wd.c: revision 1.186 date: 1999/01/17 05:46:24; author: bde; state: Exp; lines: +5 -3 Pass the unit number to the DMA cookie lookup routine and use it to look up cookies properly, at least for standard controllers. Cookies are used so that we don't have to pass around lots of args. All of the dmainit functions use the unit number so it is essential that we pass them a cookie with the correct unit number. This may break working configurations if there are bugs in the dmainit functions like the ones I just fixed for VIA chipsets. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
