In 6.1 softlockup and nmi watchdog was reworked by commit f5251db21f151cccb8bc5aeb11e9e21dcbd13fc2. So before we proceed in this direction we need to make sure we can reproduce problems we saw in 6.0. Old nmi watchdog is affectively disabled on x86_64 by commit 2d09fe61. New one, that uses perf events, is disabled in a guest since KVM does not have perf counters. 47f668319dc26a8e5f845bcb61d30b2b2e3d8893 did the same for i686. It looks like there is nothing to do for that BZ. |
