QEMU issues the ioctl(KVM_CAP_PPC_FWNMI) on the first vCPU.
If the first vCPU is currently running, the vCPU mutex is held
and the ioctl() cannot be done and waits until the mutex is released.
This never happens and the VM is stuck.
To avoid this deadlock, issue the ioctl o

Yon can get the calltrace by:
1) compile the qemu with --enable-debug

Implementations of syscalls 'mq_timedsend()' and 'mq_timedreceive()'
in 'syscall.c' use functions 'target_to_host_timespec()' and
'host_to_target_timespec()' to transfer the value of 'struct timespec'
between target and host. However, the implementations don't check whether
this conversion succeeds
This patch implements functionality for following time64 syscalls:
*mq_timedsend_time64()
This is a year 2038 safe vairant of syscall:
int mq_timedsend(mqd_t mqdes, const char *msg_ptr,
size_t msg_len, unsigned int msg_prio,
const struct timespec
This two patch series introduces functionality for two year
2038 safe syscalls.
The first patch introduces a little correction for already
implemented normal (32-bit) variants of implemented syscalls.
The second patch introduces the implementation of the
syscalls.

When converting to qcow2 compressed format, the last step is a special
zero length compressed write, ending in call to bdrv_co_truncate(). This
call always fail for the nbd driver since it does not implement
bdrv_co_truncate().
For block devices, which have the same limits, the call succeeds since
