Can someone please explain what each line here means? wlan0_rename is my wireless connection (which changes between that name and eth1 whenever I reboot.)

What do all of my wireless messages mean, and are they bad? What does the clocksource tsc being unstable cause/mean? What is rtc , and is a lost interrupt (20 that is) bad? Also, what is the cause/problem with Pidgn, and why did it segfault? It did dump a core file, but it is 47.5mb so I cannot upload it here.

EDIT: My core file for Pidgin's crash:
Output from file and size :

I can't tell you what all of them means, but I might guess correctly :)

[  405.681685] wlan0_rename: authenticated

Your wireless card has authenticated on an access point. Not bad.

[  405.681688] wlan0_rename: associate with AP 00:18:f8:42:5f:ed

Your wireless card is now trying to associate with this access point. This is the access point's MAC address. Not bad.

[  405.683255] wlan0_rename: RX ReassocResp from 00:18:f8:42:5f:ed (capab=0x411 status=0 aid=4)
[  405.683262] wlan0_rename: associated

Your wireless is successfully associated. Not bad.

[ 1500.944687] Clocksource tsc unstable (delta = -1817657700 ns)

Your time stamp counter seems to be unstable. I don't think its bad.

[ 1500.948670] Time: hpet clocksource has been installed.

High precision event timer (HPET) is installed. This is a really fast hardware timer, and usually much faster than the RTC. I don't think you really need this.

[22986.775863] rtc: lost 17 interrupts
[22986.860515] rtc: lost 18 interrupts
[22990.082509] rtc: lost 20 interrupts

This might be due to the HPET generating RTC interrupts at a rate faster than the RTC does. It seems like the handler for the RTC interrupt reports the dropped interrupts(Hello, I'm the little program that handles RTC interrupts. Sorry to tell you, but the interrupts are coming in so fast that 20 just went by before I could grab one!). I don't think it is bad. But I don't think it is good either. Too many interrupts mean your pc might be working too hard at responding on every interrupt to actually get any processing done (Interrupt storm).

[158833.063210] pidgin[22402]: segfault at 000000c4 eip b321bf5f esp b320a870 error 6

Oops. There goes Pidgin. Segfaults are usually found when an application has a pointer to a memory address it is not suppose to access. This is likely a bug in Pidgin. Not necessarily related to the previous messages. For more detail you'll have to look at the log under different circumstances (with pidgin, without, etc). You can also log this Pidgin segfault on the Pidgin forum/site.

Also, what is the cause/problem with Pidgn, and why did it segfault? It did dump a core file, but it is 47.5mb so I cannot upload it here.

Yes, please dont.

That doesn't tell me anything useful. At least you have a Linux binary :P

I'm not touching that. Too much work for me.
