 I'm having the same problem with 5.3 release and 5.4 versions too.
 
 Tried to build a version for k3b and atapicam (da, pass, etc.) to use a ata 
 dvd burner.
 
 With atapicam in-- kernel hangs on boot with an interrupt storm on em0 uhci2++
 right after it detects the ata hard drives and dvd burner.
 
 Turn off ACPI and the kernel locks in a panic at the same spot it tries to 
 start hyperthreading.
 
 Take atapicam out of the kernel and end of problem.
 
 Note: Usb ports have 'memory stick' card readers on it.   System is an 
 ASUS-P4C800-E, 2.8Ghz P4 with only PCI video cards in a multimonitor setup.
