I observed similar behaviour in case of Windows for ARM, but there was
true GSOD afterwards.
When windows is starting again its hibernated state dropped and all goes fine.

I can not understand how index in a BAT table related to s->cluster_size.
Probably there should be "cluster_index" used?
Anyway, looks like both cause uint32 truncation as result of
({i,cluster_index} * s->cluster_size)
Regards,
Mike.
der->data_off=2048, and
res->image_end_offset = 1048576, so:
static uint32_t host_cluster_index(BDRVParallelsState *s, int64_t 1048576)
{
off = 1048576 - le32_to_cpu(2048) << 9;
return 0 / 1048576;
}
Could you check this case?
Regards,
Mike.

realtime clock, this could
make sure we would not be affected by the system time anymore.
Changes v1(RFC) -> v2:
Patch 2:
- clean the code [Paolo]
- use pthread_condattr_setclock when initializing qemu-cond. [Paolo]
Patch 3:
- new added, make the qemu-sem code neater. [Longpeng]
Longpeng (M
Now, qemu-sem is based on the pthread_cond only, we can use
qemu-cond and qemu-mutex to make the code neater and the mutex
trace can be supported in qemu-sem naturally.

This patchset moves the call to kvm_irqchip_commit_routes() out of
kvm_irqchip_add_msi_route(). An optimization of vfio migration [1]
depends on this changes.

From: Longpeng
Paolo suggested adding the new API to support route changes [1]. We should
invoke
kvm_irqchip_begin_route_changes() before changing the routes, increasing the
KVMRouteChange.changes if the routes are changed, and commit the changes at
last.
[1] https://lists.gnu.org/archive/html
From: Longpeng
We invoke the kvm_irqchip_commit_routes() for each addition to MSI route
table, which is not efficient if we are adding lots of routes in some cases.
This patch lets callers invoke the kvm_irqchip_commit_routes(), so the
callers can decide how to optimize.

Sincerely yours,
Mike.
Does additional comparison make a sense here: check for LBA == 0 and
then check MBR signature bytes.
Additionally it’s easy to check buffer_is_zero() result or even print
FIS contents under these conditions.
Data looks like a part of guest memory of 64bit Windows.

from guest OS.
In other cases it can be caused by misconfigured IDE registers state
or broken FIS memory area.

or Count = 1. I thought about race
with IDE reset where registers initialized with
value SATA_SIGNATURE_DISK = 0x0101, but this means LBA=1 as well...
