Last week I upgraded from a 486DX33 ISA w/ 8M to 486/133 PCI w/ 32M as the DX33 MB would no longer work with either an Adaptec 1542CF or UltraStor 14F SCSI card. Slipped the new MB in place and all was great except I'd compiled out bounce buffers in my 2.1.0R (plus a bunch of CTM's). Added bounce buffers back and the keyboard didn't work. Took bounce buffers back out and the keyboard still didn't work. Apparently my sources were not the ones for the kernel that did work. So in went the 961014-SNAP. Keyboard works. "New" (had BIOS 1.10, downloaded 1.16 from Adaptec, burned a new EPROM, didn't help) Adaptec 2940 and ST3610N HD don't work reliably. Data on disk gets corrupted. Kernel crashes similar to the above. Crash seems to be related to disk access. "rm -rf directory" has brought it down a couple of times. Once on an NFS imported fs, bunches of times on my SCSI disk. Never on my IDE disk. Wasn't going to say anything 'till next week as I applied all the CTM patches then double-checked GENERIC and noticed a new option for the AHC driver saying some MB's didn't I/O or PIO right... Built a new kernel... got lots of "warning: comparing signed and unsigned values", and walked off with a "make world" running. Will know if that fixed it tomorrow when I reboot it with its new world and kernel. -- David Kelly N4HHE, dkelly@tomcat1.tbe.com (wk), dkelly@hiwaay.net (hm) ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
