Hello Doug,
Just to let you know that I've upgraded from linux 2.2.19pre5 to linux 2.2.19pre14 and here is an updated status.
1). My machine is a Dell optiplex 333mhz Intel with a 2940U2W AIC-7895 chipset and SCSI BIOS v1.33S2 (where S means special Dell stuff)
2). This newer patch includes the new scsi driver v5.1.33/3.2.4 instead of the old one v5.1.31/3.2.4.
3). Earlier, I emailed you about a, "Data overrun in data-in phase, tag 1; Have seen Data Phase. Length=255, NumSGs=1. sg[0] - Addr = 0x7fea380 : Length 255"
error message during bootup for linux kernels 2.2.15-2.2.19pre5.
4). HOWEVER, with this newer patch, the "data overrun" error messages disappear. I've recompiled with TCQ enabled and disabled and with the TCQ queue size 8 and 24 and no boot problem was encountered. Moreover, there wasn't any problems running it on UMSDOS with a Western Digital 9.1 Gig SCSI drive.
I wonder what changed that eliminated this data overrun problem in this newer SCSI driver v5.1.33? The Changelog doesn't seem to hint at a fix in this area.
Things look good to go.
