Hi i've got an openvox a800p01 with 1 FXO and 4 FSX i've done the following: - downloaded zaptel-1.4.7.1 > >> - downloaded the file opvxa1200.c > >> - copied in zaptel-1.4.7.1/ > >> - edited makefile adding opvxa1200 in the modules and the voice > >> opvxa1200.o : zaptel.h wctdm.h > >> - edited zaptel.sysconfig adding MODULES="$MODULES

Description: Use schedule_timeout_{,un}interruptible() instead of set_current_state()/schedule_timeout() to reduce kernel size. Also use helper functions to convert between human time units and jiffies rather than constant HZ division to avoid rounding errors.

upstream commit 2ad49887150894b9ed6a87a76b409adceee6b074 Motivated from the commit, I found that cleaner_kthread() and transaction_kthread() can result similar error since these two function can exit even though kthread_should_stop() is not true. In order to resolve the bug, break statements are changed into continue statements in order to wait until kthread_should_stop() becomes true. ---

From: Mihai Don?u <mdontu at bitdefender.com> The introspection requests (KVM_REQ_INTROSPECTION) are checked by any introspected vCPU in two places: * on its way to guest - vcpu_enter_guest() * when halted - kvm_vcpu_block() In kvm_vcpu_block(), we check to see if there are any introspection requests during the swait loop, handle them outside of swait loop and start swait again.

virtio balloon has this code: wait_event_interruptible(vb->config_change, (diff = towards_target(vb)) != 0 || vb->need_stats_update || kthread_should_stop() || freezing(current)); Which is a problem because towards_target() call might block after
