Kernel panic behavior

VRVDR-49991 modified kernel panic defaults by introducing additional panic events for the S9500-30XS platforms in 1912b.

The following additional events are available:

  • panic-on-io-nmi
  • panic-on-unrecovered-nmi

The reboot delay time that follows a kernel panic was also modified from 60 seconds to 30 seconds:

  • reboot-wait-after-panic = 30

VRVDR-52568 reverts the defaults in 1912f so the system no longer panics on the additional events. The reboot wait timer is also reverted to 60 seconds. The ability to use the CLI to change the behavior through configuration is still available, but the default behavior is different. No changes to the panic-of-oops default — it remains set.
