BSoD?

[CJ Master]

Hello,

I assume that Ubuntu has it's own BSoD, if so what is it like?

[CholericKoala]

Kernel Panic

[chris4585]

kernel panics are bad mmmmmmkay?

As mentioned, Kernel Panic, I will say I haven't had a Kernel Panic in years, and never had one while running Ubuntu.

[FuturePilot]

Out of the 2 years I've been using Ubuntu, I've only had 1 kernel panic ever. It was nothing special really. It just kind of froze and some of the LEDs on the keyboard were blinking. There wasn't any kind of error screen or anything. I guess if you happen to be on a tty when it happens you'll see some interesting looking error.

[OutOfReach]

Kernel Panic, definately. I've never had one and not expecting one soon. :)

[RiceMonster]

Never had a kernel panic.

Had a BSoD once on windows.

[Maverick321]

I had one kernel panic, but it was due to a overheating cpu. Well it was more than one but all from the same cause.

[Eisenwinter]

I have never had a kernel panic. I've had BSOD's on windows though.

[fiona-conn]

I've had it happen.

It's called a segfault.

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

In my case, I was running Second Life, at the time, alongside Emesene and XChat. The entirety of my desktop, Emesene, XChat, AWN, all froze up and wouldn't respond to my clicking. Only thing that remained running was SL, but trying to shut down the program, it was slow and eventually unresponsive.

I hit ctrl alt backspace, which exited me out of the segfault to the login screen, where I relogged in, and had to use the kill -9 command on an SL process that had remained running in the background. -.-

Not fun.

Seg Faults are not the same as BSoDs.Seg faults is just a problem with a single program.

I have lots BSoDs and only a few kernel panics.One was caused with hardy just after the first alpha (self explanatory) the rest was hardware faults with an old nvidia card.

Hello,

I think I might have had 3 so far.(Ever since I joined these forums.)

[Potency]

Just wondering... but what steps would you take to resolve a kernel panic? Would you just boot from a cd or what?

[Newuser1111]

Just wondering... but what steps would you take to resolve a kernel panic? Would you just boot from a cd or what?From booting to hard drive. It would get Kernel Panic on startup.
Restarting the computer fixes the problem.

I rarely get BSODs, but sometimes Ubuntu will crash and I'll have to restart.

o.O Really? I was told by another Linux user at the time of having the crashes I'd described that it'd been a segfault, and that it's considered the Linux equivalent of a BSOD.

Usually just a hard reboot.

What you described does indeed sound like a segfault, but it's not the same as a kernel panic. A segfault is usually just a single application crashing, while a kernel panic is the entire kernel crashing.

[Potency]

Thanks... just so i can be prepared if it ever happens to me.

[linuxguymarshall]

I want a Brown Screen of Death for Ubuntu.

[lisati]

Had a few BSODs on XP, some fixed by reseating a PCI card in its socket, some seemed to be related to some kind of "alergy" to (or incompatibility with) SP3

Had a kernel panic once or twice, about the same time the BSOD in Windows (assorted tables related to the MBR seemed to be messed up)

[Chame_Wizard]

1 Kernel panic and that was last year :lolflag:.

[-grubby]

I've had many Kernel Panics, mostly on Arch because of some weird hardware incompatibility. None so far on my current install of Ubuntu, which has been running since August this year.

[happysmileman]

Think I've only had one on Gentoo (built kernel wrong :P), not as pretty as a BSOD.

I decided to make it pretty by (instead of actually fixing the problem) finding the function for it and throwing in a load of printk()'s to make ASCII art and rebooting....

After that it was the most awesome crash ever

As other have said a segfault is different to a kernal panic, but a segfault can cause a kernel panic depending on what it happens in, a segfault in some key part of the kernel or an important driver I think would cause it, or a seg fault while booting could cause important things to not be set up right?

[Grant A.]

Chances are on Ubuntu it would be an Orange Screen of Death. The Blue Screen of Death is reserved for Kubuntu.

[securitynut]

Never had a kernel panic and don't want one either. I've had many a BSoD on windows. (reason for getting Ubuntu).

[zmjjmz]

I used to get kernel panics every other time I started my MacBook in Gutsy.
This was before suspend/resume worked, and my battery had this weird issue where it would die immediately if unplugged.

This is entirely my fault because I spilled seltzer on it.

[MaxIBoy]

I got a kernel panic when I did a botched job creating an Ubuntu remaster. Other then that, I've only gotten the occasional driver crash.

A "segfault" is a "segmentation fault". Apparently it happens when a program tries to access memory that does not belong to it. So, a segfault by nature cannot happen within the kernel, as the kernel can access all memory.

A minor kernel problem is called an "Oops", and sometimes an oops can cause a panic. Sometimes a segfaulting program can cause a panic via proprietary graphics drivers, but then the proprietary graphics drivers cause panics of their own.

[Barrucadu]

I've never had a kernel panic I didn't cause myself (I wanted to know what would happen if I killed init)

[EnGorDiaz]

never had one in windows

or a kernel panic in ubuntu

[MttJocy]

Only time I had one of those was when removing the monitor cable from the graphics card without realizing someone had borrowed the cards mounting screw felt the card slide out of the motherboard followed by a segfault in compiz and a kernel panic, presumably trying to write to the now none existent memory addresses on the grapics card..
