The synchronize cache failed is unrelated - it may even be a drive firmware
funny, and in the cases you hot unplug the card I'd expect to see it in the
trace anyway.

I'll get the pflags patch upstreamed ASAP

That probably is the issue. Seems that it was either ports or flags not being
set correctly. After tracing for a bit that was conclusion, just checking if
removing the line fixes the issue or do be need to actually bitwise shift it.
On the other hand will send a patch for the first issue unless someone wants to
write up a patch for it themselves.

First yes you can use kgb if you have a second system and can mount the
debugged system over serial. On the other hand remove this line:
ap->pflags = ATA_PFLAG_PIO32 | ATA_PFLAG_PIO32CHANGE;
from ninja32_init_one. If this doesn't fix it then close the bug as we fixed
the original issue and open another one with your other bug reports as this is
a secondary issue.

  Isn`t there any better way to debug this? If the backtrace does not give you
enough information isn`t there something like kdb that can generate core files
/ analyse variables etc.? At last I wonder if it is worth all of the work
because the SCM PCMCIA adapter seem to work quite well since
4.8.0-rc1-ARCH-26316-g65ea11e (comment #9); you can mount read and write CF
cards with it. - and I have a couple of other bugs that are pending to be filed
...
  ... for Xorg and my own programs I had at least programmed a program that
could annotate line numbers for functions at backtraces which I remember to
already have been of great help (if you do not even know the line where it
fails the backtrace may be misleading).

Most drivers need to check that was just making sure it wasn't this one. I
don't have this hardware otherwise I would have not asked you to test for me
and just give me your traces so I can debug this on my own hardware. Anyhow
there is patch below that is going to allow me to see if the ports the driver
is using during port are not pointing to NULL.

Ingvar; are you sure that your latest patch does not break the whole kernel IO
subsystem? Last time I have got stuck in the initrd (not even the kyboard was
working). Please test that patch yourself on your system and whether it boots
like this at you.

That was incorrect see if this patch helps out on top of the other patch that

OOpsla; there is something wrong about the patch:
ap->ioaddr.altstatus_addr = base + ??;

What value would you suggest to assign here?
I have seen different values being assigned here in different locations like
base + 0x8a, 0xe, 0xca or ap->ioaddr.ctl_addr like before.

4.8.0-rc1-ARCH-26316-g65ea11e dmesg without any patch: works

  Now as the previous test results started to appear strange to me I have
retested with 4.8.0-rc1-ARCH-26316-g65ea11e, completely unpatched. - and see
the CF adapter was in deed working correctly (however spying out the usual
backtrace). I do not hope that previous tests were in vain because of this
while I wonder how the recognition of /dev/sdb1 could slip through the last
time. As the card is sometimes not fully recognized on insertion I should
probably have double tested it ...
  ... concerning your latest patch I will now test it on top of a vanilla rc2.

Keep the patch that works and apply this on top, I am very doubtful that the
NULL pointer is the irq line passed but after looking some closing seems it's a
good idea to try it.

Groovy; that has resolved the issue and I can now exuberantely make use of my
SCM PC Card readers; copying, comparing and creating files from and on CF now
works fine through this card. Still there has ended up a backtrace on insertion
of the reader (including a CF) in the dmesg ...
