12.7.5 - My Soekris performs poorly The Soekris machines are nice, low-power, small and modest cost PC class systems, and many
OpenBSD users are quite pleased with them. However, it must be remembered the processors, NICs, and
other devices on the system are all chosen for low power consumption, not performance. While they are
suitable for many applications, they are not high performance machines.
12.7.6 - I get "missing interrupt" errors on my CF device With some CF systems, such as early Soekris 4801 systems and some CF adapters, the DMA support is
not properly wired up, so you might see messages such as:
pciide0:0:0: bus-master DMA error: missing interrupt,
status=0x20
In these cases, you will need to disable DMA in the
wd(4)
driver to avoid this problem. This can be done
using
ukc
to install, then
config(8)
to change it permanently:
ukc> change wd 42 wd* at wdc*|pciide* channel -1 flags 0x0
change [n] y channel [-1] ?
flags [0] ? 0x0ff0 42 wd* changed
42 wd* at wdc*|pciide* channel -1 flags 0xff0
ukc> quit 12.7.7 - Is this really new CPU supported? The issue of support is rarely the CPU itself, it is almost always the surrounding and supporting
hardware.
Most likely, yes, the latest CPU is supported just fine. The surrounding support hardware may not work
if it is significantly different than earlier versions. If you have problems with new hardware, make sure
you try a
snapshot
before making a
bug report
.
