Dear all,
I hope this is the right place to send this sort of backtrace dump.
I'm getting the following sort of dumps (below) on a 3.2.27 kernel on
an arm/kirkwood (actually DreamPlug) machine that's used as a router.

Hi.
Like many people[#1][#2], I have found out that the Linux capability
handling utilities are non-functional, and cannot be repaired because
the kernel deliberately cripples capabilities (they are reset on every
call to execve()). I have found that various people[#1][#2] have

Well, I wasn't sleepy tonight, so I produced the following patch for
Linux capabilities, which attempts to make them useful. It is
supposed to do the following (which may or may not conform with the
POSIX semantics, I don't think it matters much):

Hi. I apologize for what is surely a stupid question: I understand

to do anything worth while),

I have ECC RAM on my system and I wanted to check it, so (because
there doesn't seem to be any Linux ECC support for my P5WD2
motherboard) I wrote my own kernel module[#] to interrogate the

reported an ECC error, and a multi

I'm extremely confused as to what all the RTC-related config variables

TL;DR: the iTCO_wdt watchdog on the Asus P10S-WS motherboard, instead
of rebooting the machine, places the motherboard in a completely
nonfunctional state, from which it can be revived only by a hard power
cycle. I suspect this is a BIOS bug: seeking advice on how/where to

Is there a patch or a boot option or something which wipes all

Also, I'd like to know exa
