## Yep, the DSDT shows that 0000:00:09.0[A] (should be) on LNKA
Package (0x04) { 0x000CFFFF, 0x00, \_SB.PCI0.ISA.LNKA, 0x00 },
Package (0x04) { 0x000CFFFF, 0x01, \_SB.PCI0.ISA.LNKB, 0x00 },
Package (0x04) { 0x000DFFFF, 0x00, \_SB.PCI0.ISA.LNKA, 0x00 } })
ACPI: PCI Interrupt Link [LNKA] (IRQs 10) *0, disabled.
## though it is sort of unexpected that LNKA should come to Linux
from the BIOS in a disabled state -- assuming that
the devices on it are enabled in the BIOS.
But yes, the fact that enabling LNKB w/o pci=routeirq sure makes
this looks like a plain 'ol BIOS bug; and the fact that the
same failure is seen on Windows until the modem driver is
loaded confirms that. It also confirms that Linux is bug compatible
with Windows:-)
Perhaps we should simply automatically enable pci=routeirq
for BIOS that matches this one? Anybody care to provide dmidecode output?
