Cisco Bug: CSCul68057 - CF driver change for 5508/WiSM2

Last Modified

Feb 14, 2019

Products (1)

  • Cisco 5500 Series Wireless Controllers

Known Affected Releases

7.0(240.0) 7.4(110.0) 7.5(102.0)

Description (partial)

Symptom:
Wireless LAN Controller may encounter unexpected reload without crash file or coredump.
Console log output may include "reaperWatcher rebooting" and "!!!!! Watchdog detected LOCKUP !!!!!",
and there may be "#OSAPI-2-REAPER_WATCHER_INFO" message in syslog.

As a consequence, If we happen to hit this issue during an incremental config save, we may experience corruption or loss of some configs. If this was triggered while saving a config subsequent to a clear config or from the initial config wizard, we may end up losing all of the configs.
And if we hit this issue during a transfer download, depending on the phase of the process, we may endup corrupting an image or the ap bundle.

Conditions:
Affected S/N: 
5508: FCW1614xxxx and later
WiSM2:SAL15129XXX and later

This is due to incompatibility of previous driver with some of the flash components used after that date
