This on an multi-core Atom based appliance. Using SSD for hard-drive.
Fedora 14 OS.
2.6.39-rc* has been very flaky for me on this system (haven't tried other
machines yet), and I'm pretty sure I saw similar bugs on earlier 39-rc kernels though
they often crashed on other things as well...
I can provide more info as needed.
This is the warning that hits...
/*
* We guarantee to LLDs that they will have at least one
* non-zero sg if the command is a data command.
*/
if (WARN_ON_ONCE(ata_is_data(prot) &&
(!qc->sg || !qc->n_elem || !qc->nbytes)))
goto sys_err;
After the warning and the errors below, the system locks hard.
The same system works fine on 2.6.38 kernels.

I found someone else reporting this bug against -rc1, and folks
requested lspci -nn. It's included below. This is from a different
boot, but appears to be the same bug. System didn't lock hard right away,
but crashed shortly after I gathered this info.

And, same warning in latest linux-2.6 (no extra patches, from a few minutes ago).
System worked for a bit, then this splat:

Ok, it took a while, but I think I have this thing somewhat bisected.
Starting at commit 4cc4d24efce4672f9b0e7fa27963770ae602998f, I see hard-drive
issues. Commits right before this (in git bisect) crash in the networking code
quite often, but the hard-drive logic seems to work at least.
In later builds (ie, -rc3), the crashes and warnings are different, but
they have something to do with the file system. It's difficult to bisect
it any better because of all the instability...
Here are some console logs from a 4cc4d24efce4672f9b0e7fa27963770ae602998f boot:

hmmm... that's a merge commit. Any chance you could mark an individual
commit bad, to narrow things down a bit more? Run "git help bisect" and
check out helpful sections "Avoiding testing a commit" and "Bisect skip".

What do I want to skip or avoid testing though? Does bisect not know how
to deal with merges?
Here is the log, in case that helps:

I tried today's kernel (39-rc4+) and it seems much more stable on my
system. So, I think the problem must be fixed. It appears it was not
fixed in the plain 39-rc4, for what that's worth.
Thanks,
Ben

Hmmm... interesting. I don't know of any changes which could have
affected that but then again I've been half offline for the last three
weeks. Can you please try to boot earlier kernel and determine
whether the kernel version difference is actually making the
difference?
Thanks.

I tried the 39-rc4-wl (wireless-testing) kernel that was based off of
39-rc4, and I see hard-drive read errors there, and eventually
crashes. I didn't try Linus's 39-rc4.
Yesterday's rc4+ kernel ran fine overnight.
I had previously bisected this to a merge in post 2.6.38 code, but
I never found time to figure out what part of the merge was
funky. In general, from 2.6.38 to very recently, the kernels
have been very unstable on my systems, with multiple networking
crashes and this block level and/or hard-drive stuff causing
trouble, so it's hard to tell exactly when certain bugs
were introduced.
2.6.38 has been stable, as has 2.6.38-wl.
If there is some other specific commit you'd like me to test
I can do so.
Thanks,
Ben
