No. Sharing PCI interrupts is quite normal.
With a standard PC you can try to improve things by moving PCI cards to
different
PCI slots, trying to reduce the PCI interrupt line sharing. But with a loptop
this kind
of "fix" is impossible.
You can use the following commands to print a list of the running system's
interrupt
vector table, and which drivers are using shared interrupt vectors:
echo ::interrupts | mdb -k
echo ::interrupts -d | mdb -k
