Reboot fails: new 2.6.8 kernel-headers at fault??

If none of the more specific forums is the right place to ask

Kernel Headers

Postby Absent Minded » 2006-07-20 04:28

he relevant entries in /var/cache/apt/archives are:

kernel-headers-2.6.8-3_2.6.8-16sarge4_i386.deb
kernel-headers-2.6.8-3_686_2.6.8-16sarge4_i386.deb
kernel-image-2.6.8-3-686_2.6.8-16sarge4_i386.deb

Can't say I understand this duplication of kernel-headers. Maybe you can help me grasp the concept?


Your headers arnt duplacated ... the first listed are for NON 686,586 (PIII / PII) Optimized systems.

Just checking, ajdlinux, to make sure you are paying attention.

Well, the changelog is small:

proc-environ-race-1.dpatch, proc-environ-race-2.dpatch

[SECURITY] Fix local root vulnerability by a race in proc. See CVE-2006-362.

So it was a security update. What modules have you got loaded?

Well, I was wrong. Because just now my system failed to shut down properly while running my trusted old 2.6.15...

I find that every so often my system doesn't shutdown or reboot properly on 2.6.15, especially when KDM fails to shutdown because of some process that hasn't died yet, so I have to use the command line and then it doesn't work...

Here's the list of acpi related modules that I found, all of these are loaded or what?:
/lib/modules/2.6.15-1-k7/kernel/arch/i386/kernel/cpu/cpufreq/acpi-cpufreq.ko
/lib/modules/2.6.15-1-k7/kernel/drivers/acpi
/lib/modules/2.6.15-1-k7/kernel/drivers/acpi/asus_acpi.ko
/lib/modules/2.6.15-1-k7/kernel/drivers/acpi/ac.ko
/lib/modules/2.6.15-1-k7/kernel/drivers/acpi/container.ko
/lib/modules/2.6.15-1-k7/kernel/drivers/acpi/battery.ko
/lib/modules/2.6.15-1-k7/kernel/drivers/acpi/button.ko
/lib/modules/2.6.15-1-k7/kernel/drivers/acpi/hotkey.ko
/lib/modules/2.6.15-1-k7/kernel/drivers/acpi/fan.ko
/lib/modules/2.6.15-1-k7/kernel/drivers/acpi/processor.ko
/lib/modules/2.6.15-1-k7/kernel/drivers/acpi/ibm_acpi.ko
/lib/modules/2.6.15-1-k7/kernel/drivers/acpi/toshiba_acpi.ko
/lib/modules/2.6.15-1-k7/kernel/drivers/acpi/thermal.ko
/lib/modules/2.6.15-1-k7/kernel/drivers/acpi/video.ko
/lib/modules/2.6.15-1-k7/kernel/drivers/pci/hotplug/acpiphp_ibm.ko

Sorry, but there will be a slight delay while I put out some fires in the In Basket....I'll back with answers for you shortly!

Drat. I seem to have wandered off the path...point me in the right direction, please!

I updated my database, and then used command slocate apic | less. Results: nothing in /lib/modules/2.6.8-3-686 or anywhere else but /usr, where source code and various document files are to be found, but nothing that tells me whether I have any kernel modules involving apic. Right: no directory except /usr contains a file including "apic" in its name. Do you need a list of the subdirectories of /usr that include some sort of apic file?? I thought I would find the apic-related modules in somewhere in /lib.

Then for confirmation I tried this command: ls -R /lib | grep apic | less and got zero results. .

Over to you...

AFAIK APIC isn't a module.

Now I'm really, really confused.

I was looking for apic-RELATED modules, per your post above. Neither you nor I said apic is a module (check the exact wording of our posts). My search was for any module that included the word "apic" in its name.

Doesn't the list you provided in your post show the modules you have that fit that description, namely, "apic" is part of the name of the module? I was looking for a similar list, and I did not find anything. (That may not mean nothing is there; perhaps I conducted my search improperly. That's why I spelled out exactly how I searched -- in case I need instruction in effective search techniques.)

CMIIAW, please.

Back to basics: I assumed that the most recent change to my setup was responsible for the sudden coincident failure of the "reboot" command. That could be an example of the "post hoc, ergo propter hoc" fallacy.

We simply don't know where to find the cause(s) of this little problem -- and it IS a little problem -- so it's time to close this thread.

Thanks to all who contributed!
