File/memory corruption in 2.6.37?

File/memory corruption in 2.6.37?

[Thomas Fjellstrom]

Ever since I upgraded to 2.6.37 from 2.6.36, that kmail's folder indexes are 
being corrupted fairly regularly. Far more often than is usual (almost never). 
Several a day in fact are being corrupted. I can only imagine that this isn't 
the only corruption happening and it is worrying.

Forgot to give any kind of useful info:

System: Lenovo SL500 laptop, intel core2duo T9400 cpu, 4G ram, gm45 intel gfx

running debian sid, with the current debian 2.6.37 kernel, was running a hand 
rolled 2.6.36 kernel with autogroup applied and didn't have these issues.

The only real change has been an updated kernel, and some other misc packages. 
(not any KDE packages, have to compile it myself since debian has fallen WAY 
behind on KDE again).

Could you verify that with an hand rolled 2.6.37.2 ?

Thanks,

I suppose it won't hurt to give it a try.

Any results yet?

Which filesystem is being used?  I've seen at least one similar report
for reiserfs.

So far I haven't noticed the corruption with 2.6.37.2, and I'm using ext3. I'm 
going to test with the debian kernel again soon here to see if the problem 
come back. I was just seeing if maybe it only happens when I've been using the 
system for a long time. I tend to have a lot of issues with this laptop once 
its been running for a long enough period (typically related to the intel_gfx 
drivers leaking and causing crashes or general unstableness). I had to restart 
my laptop a couple days ago, due to it not noticing the resume image.. but I 
didn't notice any corruption before that.

Yes in my case kmail+git over reiserfs eat my data quite fast

That is really strange is a simple shell loop : while true; do sync; sleep 1; done; reduce the problem.
