I am not getting that message for any of the other devices. Here is the
output of: dmesg | grep -i msi
[ 1.533883] pcieport-driver 0000:00:0b.0: found MSI capability
[ 1.534197] pcieport-driver 0000:00:0c.0: found MSI capability
[ 1.534501] pcieport-driver 0000:00:0d.0: found MSI capability
[ 2.905219] forcedeth 0000:00:0f.0: highdma pwrctl mgmt timirq lnktim
Maybe your message comes because you have some DEBUG_MSI_INTERRUPTS flag
set or something (purely guessing here) as my other devices using MSI
are working perfectly and this has to be looked for elsewhere.
Any other info I can provide that will shed some light on the situation?
