Hubbard" Sender: owner-questions@freebsd.org X-Loop: FreeBSD.org Precedence: bulk More info... As I type this message, I'm trying an end-around that gets farther... but fails basically in the same way -- data corruption. I think I have the ``goods'' on the fact that there is an SCSI I/O problem (maybe in overlapped operations) in the 2.1 driver on the ISA 1542 driver, since this works under FreeBSD 2.0.5 on this hardware (as well as a few other OS's). Note I have a second copy of the 2.1 CD (that I borrowed) since the boot floppy trick is hanging in the SCSI driver... I need two copies so I can get the original copy of the system in memory. Set Up.. 0.) Using took my working 386/FreeBSD 2.0.5 system. put one of the FreeBSD 2.1 disk1's in its cdrom. put the other FreeBSD 2.1 disk1's in the ``target'' (486) system's cdrom make sure you have a 2.1 ``root'' floppy. 1.) Boot DOS on the 486 and then use fbsdboot to load the 2.1 kernel. 2.) Using the ftp install, get the ``dists'' from the 386 across the ethernet (and the root from the floppy) What I'm doing.... after using the local CDROM to load the kernel, the only SCSI activity is the DISK (and the 1452). So only a single device is on the bus, but whatever overlap the driver does with a single drive are occuring (We are also now generating ethernet traffic). Results... I get >>much<< further - but I eventually panic with an inode corruption. Clearly a SCSI operations is not being handled properly. This is different from an ``hang'' mind you, but I bet its related. Clem PS Maybe you guys should add me to your ``QA'' group. Clearly, I try things other folks may not ;-)
