Hi, I have been having problems with the aic7xxx driver under linuxppc (as described below) and it was suggested that I pass this problem along to you. Any help you could provide would be greatly appreciated.

I ran into this problem a couple of kernels ago, but it disappeared. Unfortunately, I'm not sure what I did to eliminate it. I tried rebuilding the sequencer code, and if that's what did it it's likely that the problem is due to the kernel including a prebuilt file that has the wrong endianness (i.e., it works only for Intel systems). This seems a bit unlikely, since the sequencer code is supplied as an array of hex bytes in a C source file. For general discussion and help on the aic7xxx driver, send a message to aic7xxx@freebsd.org. It's important that the author of the driver be informed of this (and that he know that I'm not the only one in the world who's run into it) so that he can make appropriate changes to the kernel build process, if that turns out to be the problem. I just built a new vger kernel but haven't tried to boot with it yet. I'll let you know what happens. The assembler for the sequencer code used to be available online, but I can't find it now. Look at ftp://ftp.dialnet.net/pub/linux/aic7xxx/ for the latest drivers and related tools. -Randy To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-aic7xxx" in the body of the message
