Hello Avi,
latest QEMU seems to be broken when a system emulation with flash is
started.
I did not run git bisect, but it looks like the problem started with
this change:
c5705a7728b4a6bc9e4f2d35911adbaf28042b25
Author: Avi Kivity <avi@redhat.com> 2011-12-20 14:59:12
vmstate, memory: decouple vmstate from memory API
I first noticed the problem with my AR7 emulation (not part
of official QEMU), but also got it with MIPS Malta, so I assume
that all systems with flash are broken and fail with this assertion:
/qemu/exec.c:2785: qemu_ram_set_idstr: Assertion `new_block' failed.
The function is searching for address 0x10000009 which is 0x10000000
plus an index. Without the index, the address would have been found.
Regards,
Stefan

Hello Avi,
I'm having also problems with this patch:
# VGA bank switching problems under DOS
git checkout 682a3c07f0e28d2532c911a44a9b6142d6299cc2
# OK
git checkout aad3b517a1b83561f2755dc4451596a421399c19
And commit 682a3c07f0e28d2532c911a44a9b6142d6299cc2 is the Merge commit
'c5705a7728b4a6bc9e4f2d35911adbaf28042b25' into upstream-merge.
Thnx.
Ciao,
Gerhard

A patch for this has already been posted; hopefully to be merged soon.

To test: Which patch do you exactly mean?
Thnx.

Helo Avi,
Can NOT confirm that one of these or both changes work well. So
something else is (still) wrong.
