I'm very sorry about the confusion I caused up to now. But I don't know what's
wrong with my system that worked fine for about 3 years now (at the beginning
without usage of the ncr because there was no linux driver then).
The symptoms I'm seeing are unnecessary heavy swapping when the system is
up for a longer time (at the beginning everything is normal). Now that I use
the original ncr driver the problems only appear later (this had caused me
to suspect the ncrBsd2Linux driver, which seems wrong now).
In addition to that, I'm a bit alarmed because no one else seems to see this
problem :-(
Here comes a description of my setup:
- Asus PCI/I-486 SP3 motherboard (with intel saturn chipset, ancient but good)
with ncr 53c810 on board.
- i486DX2-66
- linux kernel 1.3.9* (compiled without PCI bridge optimization)
- booting via Initial RAM disk using lilo
- original and bsd ncr driver
- all scsi-code loaded by kerneld
- Multiple devices driver support compiled in (linear and raid0 as modules)
but not used at the moment.
- libc 5.0.9 (I don't think that this matters, but still....)
- /proc/scsi/scsi says:
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: CONNER Model: CFP1060S 1.05GB Rev: 213C (the patched firmware)
Type: Direct-Access ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 03 Lun: 00
Vendor: HP Model: C1533A Rev: 9503
Type: Sequential-Access ANSI SCSI revision: 02
- /proc/pci says about the ncr:
Bus 0, device 1, function 0:
Non-VGA device: NCR 53c810 (rev 1).
Medium devsel. IRQ 9. Master Capable. Latency=128.
I/O at 0xd000.
Non-prefetchable 32 bit memory at 0xfc000000.
- At the moment the problems are starting, but the machine is still usable and
free says:
total used free shared buffers cached
Mem: 14964 14740 224 3516 280 2532
-/+ buffers: 11928 3036
Swap: 33724 12312 21412
Hmmm... this looks normal to me....
I'm a bit unsure of what to do, because the system doesn't crash and I get no
suspicious messages in the logfiles.
Does it help if I get some EIPs (and the according functions) of a running
system (by pressing Alt-Gr+Scroll-lock in textmode) when the heavy swapping
occurs?
