Kernel Panic Ensemble

Kernel Panic

http://en.wikipedia.org/wiki/Kernel_panic

Jon Hammond here in New York City folks,

I had my first case of kernel panic here on my computer and I decided it would be a good name for

a band, so here it is...introducing The Kernel Panic Ensemble !

For those of you who don't know what kernel panic is, it's way beyond my scope of technical

knowledge, but I know a little bit more about it now that I have experienced kernel panic, and

it's all about what happens in my underlying content and media on my HammondCast broadcasts on

KYOU Radio and my cable tv show The Jon Hammond Show now in 27th year on MNNTV and streaming

worldwide.

Here is the definition according to one our most trusted sources Wikipedia:

Thanks for visiting, tuning in watching and listening, sincerely, Jon Hammond

A kernel panic is an action taken by an operating system upon detecting an internal fatal error from which it cannot safely recover. The term is largely specific to Unix and Unix-like systems; for Microsoft Windows operating systems the equivalent term is "Bug check" (or, colloquially, "Blue Screen of Death").

The kernel routines that handle panics (in AT&T-derived and BSD Unix source code, a routine known as panic()) are generally designed to output an error message to the console, dump an image of kernel memory to disk for post-mortem debugging and then either wait for the system to be manually rebooted, or initiate an automatic reboot.^[1] The information provided is of highly technical nature and aims to assist a system administrator or software developer in diagnosing the problem.

Attempts by the operating system to read an invalid or non-permitted memory address are a common source of kernel panics. A panic may also occur as a result of a hardware failure or a bug in the operating system. In many cases, the operating system could continue operation after memory violations have occurred. However, the system is in an unstable state and rather than risking security breaches and data corruption, the operating system stops to prevent further damage and facilitate diagnosis of the error.

The kernel panic was introduced in an early version of Unix and demonstrated a major difference between the design philosophies of Unix and its predecessor Multics. Multics developer Tom van Vleck recalls a discussion of this change with Unix developer Dennis Ritchie:

I remarked to Dennis that easily half the code I was writing in Multics was error recovery code. He said, "We left all that stuff out. If there's an error, we have this routine called panic, and when it is called, the machine crashes, and you holler down the hall, 'Hey, reboot it.'"^[2]

The original panic() function was essentially unchanged from Fifth Edition UNIX to the VAX-based UNIX 32V and output only an error message with no other information, then dropped the system into an endless idle loop. As the Unix codebase was enhanced, the panic()function was also enhanced to dump various forms of debugging information to the console.

[edit]Mac OS X

Mac OS X 10.6 kernel panic.

Kernel panics also appear in Mac OS X. These can appear while booting up or when using an application. Once they show up they tell the user that they need to reboot the system (except for versions below 10.2).^[3] They vary from version to version:

• 10.0 - 10.1.5: The system prints out numbers and words detailing the error on-screen and then the system becomes unresponsive.
• 10.2 - 10.2.8: Similar to the current versions of the kernel panic except the text is more spaced out and the background is pink.
• 10.3 - 10.5.8: The background is now black, but with the same language translations and the same text as version 10.2.
• 10.6 - 10.6.5: The text is different and now features a Spanish language translation.

In all versions above 10.2 the text is in front of a standby symbol and is not full screen. Debugging information is saved in NVRAM and written to a log file on reboot.

jon Hammond Band theme song LATE RENT performed first half in Birdland Hamburg with tenor saxophonists Lutz Buechner of NDR Big Band radio band and Gabriel Coburger. Jon Hammond is playing his XB-2 Hammond organ he went around the world with many times. At Jazzkeller Frankfurt Jon is playing his XK-1 Hammond organ. The famous Jazzkeller Frankfurt is the place for Jon's annual "Musikmesse Warm Up Party" with Tony Lakatos tenor saxophone from hr-Bigband on guitar Joe Berger aka "The Berger-meister" and long time Jon Hammond Band drummer Heinz Lichius kicking off the Musikmesse. April 5th 2010 Jon Hammond will celebrate 25 years Musikmesse at Jazzkeller Frankfurt and special guests. Swingin' Funky Jazz and Blueshttp://www.jonhammondband.com
