Subjectlinux 2.2.19pre14 SCSI v5.1.33 patch AIC7895 comments.

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.
