[Ubuntu-x-swat] [Bug 585765] Re: Ubuntu 10.04 random freezes

2010-08-05 Thread Morgan Gangwere
I cannot back that up.

I've tried it on a Coppermine box, and it still causes the random crash
syndrome.

This has something to do with a kernel-level patch, it seems. Anyone
tried running a way upstream (2.6.35) kernel?

[Ubuntu-x-swat] [Bug 585765] Re: Ubuntu 10.04 random freezes

2010-08-02 Thread Morgan Gangwere
I've had this problem and I've reliably strace'd the offending thread
(usually via SSH).

It seems to be locked on the general pattern of an futex with a NULL timeout:
futex( ... , FUTEX_WAIT_PRIVATE, NULL , ... , 

Backtracing the process shows from gdb:
0: __kernel_vsyscall ()
1: ?? () in libc6.so.6
Backtrace stopped: Corrupt stack.

I've been able to stroke the bug by compiling Enlightenment (DR17) with
the Eweather module, setting its provider to google, clicking apply
and then close. This will lock the system fairly reliably.

It seems that if init gets this futex call down the line, it will
/stall/ the system.

I suspected it was bad RAM, so I ran Memtest86 and it came up with bad
RAM at first, so I swapped out and I'm now running on 256MB of RAM (max
on this box is 385MB) and the bug still persists, so RAM corruption is
not something thats happening on hardware.

I will see if installing the 2.6.32.11 kernel helps -- Currently I'm on
a 2.6.32-15 compiled for SMP and Preemptive and optimized for Coppermine
chips (Pentium 3 M here)

sarcasm 5 years of this, is going to be a little insane./sarcasm

Boog.
