I posted a couple of months ago regarding enabling libata.atapi on a
Digital Alpha 164LX, equipped with a Silicon Image 3114 controller. I
decied to give kernel 2.6.16 (release, was previously using rc-1) a
shot, and it no longer longer panics. I still have a Lite-ON DVD ROM
drive connected via a sil3611 bridge to port number 4, hoping that I
can avoid using the onboard CMD646.
No panic this time, though it appears to throw a machine check. The
system continues all the way to multi-user, and the Maxtor drives are
usable. Hope the attached dmesg helps. Let me know if I can be of
any assitance.
Can you build your kernel with ATA_DEBUG set and post dmesg? Just
change #undef ATA_DEBUG to #define ATA_DEBUG at the top of
include/linux/libata.h
For the SiI 3611 bridge + ATAPI devices, maybe the ATAPI_ENABLE_DMADIR
workaround should also be turned on as well. (in linux/libata.h)
My JMicron 20330 bridge + SiI 3112 can handle ATAPI DMA without
the ATAPI_ENABLE_DMADIR workaround. However, the SiI 3611 bridge seems
need it.
Is there any way to make this thing automatic? 'Recompile with #define
tweak if you have some invisible bridge chip' doesn't sound too hot.
