[9fans] venti sync fixed?

Hi,

I installed a Plan 9 from a rather recent cd image (about two weeks old).
With fossil+venti. Everything seemed to work well, however, after the second
boot, I got the same venti sync problems as others have reported here.

Now. On IRC it was rumoured that this issue was found and perhaps fixed. Is
it? Could there have been a way for me to find out myself if this has been
fixed? Is there a CHANGELOG for kernel/fossil/venti?

unless by "recent" you mean yesterday, you should try
again.  there has been a lot of change in the last month.

Here was no rumor on IRC. Russ just fixed it:
http://plan9.bell-labs.com/sources/patch/applied/nventi/readme
Copy files from sources and rebuild it you want to test.

Ah, gotcha. I just tried with a very recent image, and had the same
unfortunate behaviour.

Any guesses how soon this fix will end up in the install CD?

Today's ISO does not seem to fix the problem on a qemu install.
This is what I did:

fetch the iso
verify (md5 387cb470f2c46e5f8116ef7419086a05)
bzcat < plan9.iso.bz2 > plan9.iso
qemu-img create -f qcow2 img 10G
qemu -monitor stdio -vnc :2 -cdrom plan9.iso -boot d img

Then a usual install choosing fossil+venti.
On install completion restart qemu.

qemu -monitor stdio -net tap -net nic -vnc :2 img

Login as glenda.

kill timesync|rc	# as it thinks it is Jan 2, 2000
ndb/cs -f /lib/ndb/local
ip/ipconfig
ndb/dns -r
aux/timesync -n <local-ntp-server> # back to the present!

cat >> /rc/bin/termrc.local
TIMESYNCARGS=(-n pool.ntp.org)
ndb/cs -f /lib/ndb/local
ip/ipconfig
ndb/dns -r
^D
fshalt
#wait for it to finish
^t^tr

On reboot system pauses at ...init...sync...  After a few
minutes verify there is no disk activity due to qemu on the
host system.

If it matters this is on a qemu 0.9.0 (for i386), without
kqemu, run on a 64 bit mode freebsd on amd64.
