Hi,

Look like I have a problem here..

When the SERR* line on the PCI bus is asserted, the application
which was performing the transaction is supposed to get a SIGBUS,
right? What is the right way for the OS to find out that SERR* was
asserted besides polling the status register in the host bridge?
I expected the host bridge to generate a machine check exception
or something (on PowerPC, that is), but it looks like GT-64260A
just ignores the SERR* - no exception, no machine check. I scoured
the docs but found no relevant hints.

The host bridge is GT-64260A. The board is MVME5500.
The CPU is PowerPC 7457.

Thanks, all
