I tested some more and found this.

It is XFree86 4.1.0 DRI (tdfx driver) related.
During my first run I used the 2.4.5-ac14 kernel DRM module.
Now I am running with the latest DRI trunk DRM module.
Both show the same symptoms.

After system and first Xserver start everything is fine.

Yes, this is nasty. The appended patch fixes that. (I am not really
happy to need the PG_marker flag for writepage.)

The patch also fixes two other problems:
- shmem_file_setup has to check the given size. Else we can corrupt
  kernel memory on 64bit machines. (Thanks to Oliver Paukstadt for
  detecting this)
- shmem_remount_fs does not initialize the parameters and thus
  corrupts the sizes (detected by Joris van Rantwijk)

Alan, please apply.

Sort of necessary when you have 1gb of RAM. My machine is also a dual
CPU box.

Well, I'm running XFree86 4.1.0 DRI with the Radeon driver and I don't
show the symptoms. I use the Radeon module from DRI on SourceForge.

Have you tried it with CONFIG_HIGHMEM in the kernel?

Al,

the pre2 didnt boot on the POWER3 SMP box. pre3 does (runs in 32bit
mode).
It could be a compiler bug because we have some trouble right now with
our toolchain on ppc32.
Right now it runs pre3 fine with a binary from the same compiler etc.

I have seen this only on that box.
Is it possible that a ppc64 writes some bogus values to the disk? I had
a ppc64 binary running but I wasnt too excited about it because it
misses some essential stuff like autofs. So I booted the 2.4.2 ppc32
kernel again with no trouble for a while..

If you look closely, some of the good things in 2.4.6-pre3 were backported
by Marcelo and included in 2.4.5-ac15

But wouldn't be safe/possible/viable to merge 2.4.6-pre partially, excluding 
the page cache stuff for the moment?
IMHO, the 2.4.6-pre has important improvements, and it would be difficult to 
merge to it later.
Just a stupid opinion. No offenses.

Which is odd since all my machines are big-endian too.

It might smell of a compiler bug...

Nah - just that 2.4.6-pre1 was the version where ext2 patch went in.

I have 2.4.6-pre3 running. Machine is a PowerMac clone with a G3 CPU.
It gets loads of bogus interrupts (known problem with this machine),
but otherwise runs fine (that is, for the time being).

OK, after looking at the bug report things smell very strange:

	* kernel had barfed on lookup for /dev/console.
	* kernel had found /dev - right inode number, etc.
	* read_cache_page(inode->i_mapping, n, ext2_readpage) on it
gave all-zeroes for each page within first 32Kb (size of /dev on box in
question).
	* filesystem is not corrupted.
	* all that stuff had happened with cold caches.
	* kernel was 2.4.6-pre3 + some unspecified modifications.

Very odd. Could somebody try vanilla 2.4.6-pre1 on a PPC box? I _really_
doubt that it might be an architecture-specific problem in directory
code - it would simply fail the lookup for  /dev in that case.

I'll try to find a PPC nearby, but it may be tricky on weekend. So if
somebody wants to help... Notice that problem was on read-only mount,
so it can be tested without risking fs corruption - just try to boot
with init=/bin/sh and do ls -lR, etc.

Huh? By the time when ext2 directories come into the game you are _very_
far into the boot sequence. At which stage does it fail?  Does it fail
with root on minixfs/reiserfs/etc.?

It has been working relatively well for me in benchmarks (I'm actually
using 2.4 ext3 for my real filesystems, with backups of course ;-).
Performance of the page-cache directories up for directory operations,
but strangely file read performance is down.  Anyone else noticed this?

I saw this repeatedly using the reiserfs mongo benchmark.

Cheers, Andreas
