Persistent storage for a kernel's "dying breath"Persistent storage for a kernel's "dying breath"Posted Apr 1, 2011 19:20 UTC (Fri) by cbf123 (guest, #74020)In reply to: Persistent storage for a kernel's "dying breath" by rwmj Parent article: Persistent storage for a kernel's "dying breath"
If the vendor provided storage for ERST, then pstore would work on a normal PC.
If no hardware storage is available, the next best option is to use "kexec -p" to set up a recovery kernel that uses kexec to take over on a panic. The init scripts can then be modified to detect when they're running under the recovery kernel, and they can just dumps the original kernel memory to disk and then reboot.
