Sorry for bumping this thread after a few months, I just wanted to report
that I recently built a mainline 4.19.87 kernel with GCC 7.4.0, (playing
with some Buildroot thing) and I think I ran into exactly this issue on my
A1200. Mine runs with Blizzard 1260, 128MB RAM, and some SD2IDE adapter,
nothing fancy. Same setup works very stable and without problems under
AmigaOS, and actually, also NetBSD (although I haven't run that for a
while). I was just curious if there was any follow-up or maybe a solution
to this issue.

All previously discussed symptoms also match my observations on my
hardware, like say, PCMCIA card inserted or not makes no difference.

If that's extra info, the same kernel works flawlessly in FS-UAE (with an
emulated A1200 IDE controller), so the problems only occur on real
hardware.
