5.3 interrupt storm (atapicam) and I/O error

Not sure what to think about this yet but it definitely has something to do
with having my ATAPI CD connected to the 2nd channel of my Promise Ultra 133
TX2 adapter (PDC20269). If I disconnect the cable from channel 2 the kernel
will boot with atapicam enabled. I don't seem to be able to use my
motherboard's embedded EIDE controller with the Promise adapter installed. I
don't see any obvious I/O or interrupt conflicts, but I also don't have too much
control over it with this old SuperMicro mainboard.
Seems odd to me though, since this all worked on 5.2.1. Open for suggestions,
but for now I'm going to try to track down the SCSI I/O error problem so I can
get some CD burning done (critical system backups) and then I'll see if I can
try to figure out if this is an EIDE driver issue or a atapicam issue.
If anyone comes up with anything in the meantime... please YELL!
