>Description:
A kernel with esa(4) will freeze the machine while booting, the
last message is:
esa0: interrupting at irq 5

Normally this would be followed by:
esa0: ac97: SigmaTel STAC9721/23 codec; 18 bit DAC, 18 bit ADC, SigmaTel 3D


There are two messages that hint to bad interrupt routing:

pciintr_link_init: bus 2 device 3 link 0x61: bad irq bitmap 0x0020, should be 0x
def8
pciintr_link_init: bus 0 device 30 link 0x61: bad irq bitmap 0xdef8, should be 0
x0020

and refer to the follwoing devices:

esa0 at pci2 dev 3 function 0: ESS Technology Maestro 3 PCI Audio Accelerator (r
ev. 0x10)
ppb1 at pci0 dev 30 function 0: Intel 82801BAM Hub-PCI Bridge (rev. 0x02)

And older -current (4.99.37) works fine with esa(4).

>How-To-Repeat:
Run -current on a Dell Inspiron 8000
