Freebsd/Xen: pcifront: IRQ resource allocation failed
...f000-0xfaffffff,0xfae00000-0xfaefffff irq 16 at device 5.0 on pci3
csa: card is Turtle Beach Santa Cruz
But going ahead IRQ resource allocations fails, before interrupt
handler can be setup.
I found that it fails in "rman_reserve_resource_bound"
Because: r = TAILQ_FIRST(&rm->rm_list) = is still NULL , as it was
initialized.
Here is the stacktrace:
(gdb) where
#0 rman_reserve_resource_bound (rm=0xc07b3de0, start=16, end=16,
count=1, bound=0, flags=4, dev=0xc0d8f700)
at ../../../kern/subr_rman.c:282
#1 0xc01747bc in rman_reserve_resource (rm=0xc07b3de0, start=16,
end=16...
