Hi,
I have a machine with (see lspci at the end):
* intel motherboard (82443BX + 82371EB)
* DEC PCI-to-PCI bridges (0x0022 0x1011)
* several communication cards behind the bridges.
The DEC bridges are not recognized at boot (this is a 2.4.18-5 Red Hat
SMP kernel):
Unknown bridge resource 0: assuming transparent
Unknown bridge resource 2: assuming transparent
Unknown bridge resource 2: assuming transparent
Unknown bridge resource 2: assuming transparent
...
Limiting direct PCI/PCI transfers.
The communication cards are used through a STREAMS driver, which
does a lot of iomem r/w short operations (read/writeb/l/w).
When several of those communication cards are used simultaneously,
the box becomes very loaded.
Tracing this seems to point in the direction of errors in PCI
transfers when accessing the communications cards over the bridges.
Does anyone encountered this problem before ? Is there a way to
"configure" the PCI-to-PCI bridge ?
Thanks.
Stelian.

Congratulations, you have one of the most popular and divergent
devices ever.
Usally the fix for your card breaks a lot of other ones.
Seen this many times already and amused to see this again ;-)

Does this mean that a fix exist ?

Before posting this I did my homework and failed to google anything
relevant.
Care to explain what exactly the problem is, and any workarounds I
can try to solve it ?
Thanks.
Stelian.
