Hi, My motherboard (EVGA X58 Classified) has a JMicron JMB363 SATA300/PATA controller and it seems to be working fine with FreeBSD as long as I don't try burning a DVD or a CD with my PATA DVD burner, which is the only device hooked to the controller. However, when I try burning a CD or a DVD with either cdrecord or growisofs, I get the following: interrupt storm detected on "irq17:"; throttling interrupt source interrupt storm detected on "irq17:"; throttling interrupt source interrupt storm detected on "irq17:"; throttling interrupt source interrupt storm detected on "irq17:"; throttling interrupt source interrupt storm detected on "irq17:"; throttling interrupt source interrupt storm detected on "irq17:"; throttling interrupt source interrupt storm detected on "irq17:"; throttling interrupt source interrupt storm detected on "irq17:"; throttling interrupt source ... I have seen a few emails on the mailing lists from people having the exact same issue with this controller 2 years ago, but I could not find any helpful reply. Is there any workaround for this? Thanks!
