>Description:
On 5.0.1 miniroot, any floppy access (at least against /dev/rfd0a)
causes timeouts and hard errors (due to lost interrupts?)
on SPARCstation 1+.
On 4.0.1 miniroot it works fine.

It looks sys/arch/sparc/sparc/bsd_fdintr.s still has
old MD softintr stuff so it should be updated to
newer MI softint(9) API.
sys/arch/sparc/sparc/amd7930intr.s has the same problem.
I've tried the following dumb patch but it causes a weird panic,
so maybe I hope someone[tm] who knows sparc asm take a look at this..

Okay, the following patch (disabling "fast trap" hander?)
could be a workaround at least on my SS1+.
audioamd also works.
Is it okay to commit this for workaround?

Build miniroot binaries for sparc with -Os to shrink instfs.tgz
for the second boot floppy which use miniroot objects.
This is workaround for PR install/42146, and ok'ed by mrg@.
Don't try to read disklabel to check FS_RAID on floppy boot since
reopening floppy could cause Data Access Exception later.
Fixes PR port-sparc/42186, ok'ed by mrg@.
Disable "fast trap" handlers which invoke software interrupts
in sparc/amd7930intr.s and sparc/bsd_fdintr.s until they are
rewritten to adapt new MI softint(9) API.
No particular comments on PR port-sparc/42192, but
this fixes timeout problem on floppy access on my SPARCstation 1+.
XXX: floppy support on sun4m seems to have another problem (data overrun).
Use /dev/fd0a rather than /dev/rfd0a to read instfs.tgz image from floppy.
It looks newer (appearred after 1.6) gzip tries to read less than DEV_BSIZE
(to check header?) so we can't use raw device directly.
(note sparc bootfs ramdisk doesn't have dd(1))
Workaround for PR port-sparc/42193, and would also fix PR install/28734.
Explicitly clear AUXIO4M_FTC bit in FTC_FLIP macro used on
pseudo-dma for floppy, as well as AUXIO4C_FTC bit for sun4c.
A comment in the macro says AUXIO4M_FTC bit is auto-clear,
but my two SS20s (including compatible) with 150MHz hyperSPARCs
get data_overrun without it, and no bad side effect on SS5
(works with and without this change).
Closes PR port-sparc/42516, which is the last one of a bunch of
floppy issue on NetBSD/sparc since NetBSD 2.0 days. See
http://mail-index.NetBSD.org/port-sparc/2009/12/20/msg000484.html
