(64-bit) linux 3.10 and nouveau oddity
Due to GPF problems I've been having with wheezy's linux 3.2, I decided to try
testing's 3.10 kernel (only installed the newer initramfs and 3.10 pkgs).
Yesterday it ran fine all day, even built my firewall system without a lick of
the troubles I've been having with 3.2. (So the GPF problem might be a linux
3.2 bug. But that's fodder for another thread.)
[The log I present below is a contiguous section of syslog. There was nothing
useful in messages.]
Today, I booted, read a forum thread about someone wanting to buy a new system
and disabling CPUs. "Huh," thought I. "I wonder if disabling CPUs in the
running system changes power consumption." I've toyed with disabling and
enabling CPUs on prior versions of Debian with no trouble, so I figured
there'd be no harm. Hah!
So I disabled CPUs 3-1 on my quad Phenom II. The immediate result was the
message:
----
Nov 5 12:37:45 playground kernel: [ 2314.586965] do_IRQ: 3.65 No irq handler

Nov 5 12:37:45 playground kernel: [ 2314.587039] smpboot: CPU 3 is now

Nov 5 12:38:11 playground kernel: [ 2341.205069] smpboot: CPU 2 is now

Immediately xterm started (re)displaying quite slowly. Otherwise, the system
seemed to be OK.
But after a while (especially after I tried to start iceweasel), it seemed to
hang. Then my X session disappeared and some nouveau messages appeared. So I
switched to a text console; this took a while. It, too, kept hanging and
unhanging. And the display would switch to show nouveau messages, then the X
display would reappear a few seconds later, then the text console would appear
in a couple seconds. And I'd have maybe a half-second to type stuff in the
console (but it did seem to buffer keystrokes). The mouse was inoperative. I
eventually rebooted to clear the problem.
Is it fair to say this is a bug? In *something*? Or just an incompatibility
between Wheezy and the newer kernel?
I'm not complaining, mind you. Like the doctor said (after the patient
groused, "Doctor, it hurts when I do dis"), "Well, don't do dat." Or, as the
character Spock was known to intone, "Curious."
