Sometime between rc6 and rc7 all filesystem I/O started using 100% CPU,
usually on the order of 60% sys, 40% user.
I've tried this with each of ext4, jfs and btrfs filesystems. All show
the same issue.
Using dd(1) to read from the block specials directly works as well and
as fast as it always has; only reading or writing to mounted filesystems
is affected.
Box is 32-bit x86, PentiumIII-M; drives are ide using libata.
If the btrfs fs is mounted, the slowdown is enought to trigger the
hung_task call trace (120s) on the btrfs-transac process.
But the regression is just as apparent when only jfs and ext4 are mounted.
The only filesystems I've found which avoid the regression are tmpfs and
devtmpfs.
I didn't have time to write up a report when I noticed this in rc7 but
had to boot back into rc6 for work.
Some of the commits since rc7 looked like they might have addressed this
regression, but it persists in rc8.

I have created the bug entry at http://bugzilla.kernel.org/show_bug.cgi?id=15306
for your report.

Could you please hit sysrq-l a few times during the high CPU usage and
send us the results? Also, please send along the full dd command line
you are using and how much ram your system has.
(Even better would be running perf record <your dd command line>, if
you're willing to setup perf)
Thanks!

While getting re-aquainted with perf, and after upgrading to the current
version, I see that do_page_fault, unmap_vmas, get_page_from_freelist,
handle_mm_fault, __do_fault and T.1339 tend to get the most time when the
kernel is spinning.
T.1339 is in this part of kallsyms:

suggesting that T.1339 is part of sched.
This leaves the impression that the issue is related to either
scheduling or paging.
I don't see any commits in the rc6..rc7 timeframe which stand out
as likely suspects.

dmesg? lspci -vv?
We have an AGP related issue with WC/UC paging that might be related,
but I'd need more info.

Are you sure you're not running with any of the debugging options
enabled? I see the same, but I have debugging enabled (rawhide
kernel).

Are you sure you're not running with any of the debugging options
enabled? I see the same, but I have debugging enabled (rawhide
kernel).

OK. I do use radeon kms (r100).
On a lark, I tried out a non-kms boot this morning, but X never started;
I was going to update all of the user-mode code (dri2, mesa, x, the ati
driver, etc) before tyring again to check whether kms was required to
hit the issue. That takes a few hours to do on this box.

The only reelvant part of dmesg are of the form:

I've just sent a pull req to Linus
http://bugzilla.kernel.org/show_bug.cgi?id=3D15328
this
http://bugzilla.kernel.org/attachment.cgi?id=3D25107
patch.
The relevant piece of dmesg is at the top ;-), where
it states if you have PAT support or not, but I
suspect if you try this patch it'll fix it.

Oh. I thought you were referring to errors....
Anyway, no, the p3m does not support PAT:
[ 0.000000] PAT not supported by CPU.

That patch does indeed fix the regression here.
