There are two drivers for 9load anfd kernel.
In /sys/src/9/pc/sdiahci.c file, there is a
wakeup(&d->portm);
call just after
clearci(d->port);
line in checkdrive() function.
However, there is no that call in /sys/src/boot/pc/sdiahci.c file.
Is this intended ?
If so, what it does mean?

i would say that's likely a bug, and it's not true in
my current driver. it's a shame that geoff hasn't
picked up the newer stuff.
my current versions are
/n/sources/contrib/quanstro/root/sys/src/9/pc/sdiahci.c
/n/sources/contrib/quanstro/root/sys/src/boot/pc-e820/sdiahci.c

i have not been able to get 32-bit modes working
with vesa, but 16 bit modes do alright. i think there
may be some sort of (frame) buffer calculation that's
off. large images can crash one's terminal, too, even
in 16-bit mode.
previously i had an nvidia card working in 1600x1200x32,
but that was a agp card. i don't have any agp systems
left.

Don't be so frastrated.
If you didn't work on ahci driver, we cannot use SATA drive as fast one.
I'm very thank you.
I didn't use your new driver, because I'd like to check the present state
of being distributed Plan 9 system. Why so little number of people tries it?
I notice another problem, too.
The vga cannot be used as more than 8 depth, which I tested only
nvidia and vesa drivers.
Anyone tested it?

i apologize for the tone of this.
i'm frustrated with ahci problems. i think
many of them have been fixed, but there
are good reasons for the lag. and many
are my fault.
sorry, geoff.
and sorry for the noise on the list.
