error message cx88_alsa: IRQ loop detected, disabling interrupts

Hello,

since kernel 4.14.11 I notice these error messages every 5~6 reboots in dmesg :

[   59.372818] cx88xx: cx88_print_irqbits: core:irq aud [0x1001] dn_risci1* dn_sync*
[   59.372824] cx88xx: cx88_print_irqbits: core:irq aud [0x1001] dn_risci1* dn_sync*
[   59.372830] cx88xx: cx88_print_irqbits: core:irq aud [0x1000] dn_sync*
[   59.372835] cx88xx: cx88_print_irqbits: core:irq aud [0x1001] dn_risci1* dn_sync*
[   59.372840] cx88xx: cx88_print_irqbits: core:irq aud [0x1001] dn_risci1* dn_sync*
[   59.372846] cx88xx: cx88_print_irqbits: core:irq aud [0x1000] dn_sync*
[   59.372847] cx88_alsa: IRQ loop detected, disabling interrupts

I have 3 PCI cards :

- a sound card Yamaha Corporation YMF-744B
- a tv card dvb leadtek winfast dvb-t 1000
- a tv card dvb leadtek winfast dvb-t 1800h

and a PCI express sata controler card Jmicron,

despite these error messages all seem ok, I want to know why I have suddenly these messages in dmesg ?

my motherboard is a gigabyte GA-P35-DS3L, CPU intel core 2 quad Q9650

thanks
