Kernel panic – not syncing: Aiee, killing interrupt handler!
After a successful CLI command entry, the system crashes and the message displays. For ex-ample:
1. Upgrade to the S6010 bootloader and Uboot was successful.
2. The S6010 Web interface HTTP shows as failed.
3. Log into the USB console, and enter the command
show ip config
. For example:
>
show ip config
IP management configuration:
IP management state no such object.
>
show i
4. After entering “
show I
”, the system crashes.
A ‘kernel panic’ is an error from which the OS cannot quickly or easily recover. It applies primarily to
Unix-based systems. In other systems, the equivalent of a kernel panic is known as blue screen of death,
sad Mac, or bomb. In Windows 3.x, this sort of error was called a ‘general protection fault’.
To recover:
1. Check for these kernel panic causes:
a. An inappropriate attempt by the OS to access or write to memory,
b. A software bug or malware,
c. Failure or improper installation of RAM chips, hard disk damage or data corruption, or
d. A defective microprocessor chip or incompatible device drivers.
2. If the problem persists, contact Technical Support.
Cannot find new IP address
DHCP issued address is not being displayed
IP Address Wrong
If the DHCP client is enabled on the IONMM
MAIN
page, there is no easy way to determine the new IP
address. If DHCP client status set to “enable”, the value of “ip address” shows the last IP address, not
the current dynamic allocation IP address.
When a “
show ip-mgmt config
” command is entered on the CLI, the previous “fixed” IP address is still
returned. If a Fully Qualified Domain Name is used on any of the IONMM pages to access other devices
(TFTP, SNTP, or Radius), or to ping another PC, they will fail because of an internal sync problem when
getting the IP settings from the ION system when the DHCP client is enabled.
1.
Disable the DHCP client and set the DNS server; the problem resolves. (If you enable the DHCP client
and then set the DNS servers via the Web interface, this issue may occur due to the internal sync
problem noted above).
2.
