Some time ago I had a whine about sio silo overflows, and the concensus here
seemed to be a combination of "it's your fault" and "who cares?".
Subsequently, I've ripped out the SCSI disk from my trusty 486 and stuffed in
an IDE on a VLB controller which also happens to include 16550 UARTs. I've had
no problems with silo overflows up until today when I chanced to be using an
external SCSI disk at the same time as dialling-in. Behold, unbelievers, the
silo overflows are back...
My current rather stripped system contains a no-name VLB IDE+I/O card, and an
Adaptec 2842 VLB SCSI controller. The 16550A's are detected, but now they're
on the IDE card, not on a 2*serial card, and a bus mouse has replaced the
serial mouse so I'm only using one sio. I'm using dip to dial-in. Using the
IDE disk is OK. Using the SCSI tapes is OK. But using the SCSI disks gives:
Oct 30 20:29:59 clover /kernel: sio1: 1 more silo overflow (total 16)
and the like, every time.
FWIW.
Ian.
