I can reproduce this too on ext2, so this does not seem to be FS related. 

However, I do not get this error messages, the patch runs just fine,
but corrupts all files it touches, leaving them to be all a bit less than 
1MiB of size, and all exactly the same size.

There is no filesystem corruption however, e2fsck runs just fine without any 
error. Just the files are all damaged. I looked inside them, and it seems 
huge parts of other files from the patch have been "attached" to them.

ACK, for me too; as well as 2.4.18-rc2-ac2 for me. The breakage starts with
2.4.18-ac1 here.  Plain 2.4.18 from Marcelo works fine as well.

What compiler firstly, and what I/O subsystem. Are you using highmem,
did you build from a clean tree ?

I also think your report is unrelated to the reiserfs one. 2.4.18 proper
and -ac have a small reiserfs fix which is a viable candidate for 
reiserfs funnies while what you report is somewhat different


The actual differences between 2.4.18-rc2-ac2 and 2.4.18-ac2 that are not
in 2.4.18 are:

Maybe a candidate
	shared memory filesystem fixes (also used for sys5 shm
		and anonymous shared maps)
		[copy mm/shmem.c from the working -ac to the current -ac 
		 and retest]
	Small pnpbios update (only relevant if building with PNPBIOS)
		[Build without PNPbios and retest]

Wildly improbable
	Correct NULL check in the sd scsi code
	open fix for ps2 driver

Hw specific (check your hardware and config and you can rule these out I guess)
	JFS specific fixes
	A sparc64 specific compile fix
	An off by one fix for loop that only affects using a specific
		option with maxloop=256
	Patches that only impact users of nbd
	An AMD ELan specific driver for watchdog - no affect on others
	Locking fixes for the softdog driver
	A serverworks specific ide=nodma fix
	LS220 experimental code (which shouldnt be enabled or matter)
	Tiny tweaks to the margi DVD card driver
	Ifdef of two lines specific to promise sx6000 raid
	3c359 token ring driver (doesnt touch generic code)
	olypmic token ring specific locking change

Hi Alan and folks,

gcc 2.95.2, I/O subsystem is PIIX4 IDE here. No problems with "pure" reading 
and writing however, so it really seems to be connected to something special 
done by patch. Build was fresh from a clean tree.

Perhaps - but strange both are only triggered by "patch"? Or maybe the 
reiserfs errors are later consequences of the same problem.

Will try this now, sounds possible - but does patch really use shared memory?
I will try to narrow it down a bit. There also were some changes to 
mm/memory.c between 2.4.18-rc2-ac2 and 2.4.18-ac1. Also a possibility?

> 	Small pnpbios update (only relevant if building with PNPBIOS)
> 		[Build without PNPbios and retest]

Have bios enabled in all kernels, will try without. But there were no PNPBIOS 
changes between the working 2.4.18-rc2-ac2 and the failing 2.4.18-ac1, so
I would rule this out.

> Wildly improbable

Not using sd driver or ps2 at all.

Use nothing at all of them, just compiled most things as modules, which are 
not loaded.

Could be - as far as I can tell they are also in vanilla 2.4.18 (the
ptrace ones)

The changes I see here between them do not seem to be related to ptrace. But 
I think I already found one possible glitch by manual inspection there. Both 
kernels are compiling just now so I can test later.

Its the same thing - its an ugly Gcc extension.

One other person who reported the problem reports 2.4.18-ac2 is ok, in
which case it might be the slight mismerge in ac1 tho I'm puzzled why.
Certainly my testing here is behaving so far

There were no problems with 2.4.19-pre1, to which I reverted, pulled
the full 2.4.18, and patched back up to 2.4.19-pre1-ac2.

Booted into 2.4.19-pre1-ac2.

Patched back down to 2.4.18 and then back up to 2.4.19-pre1-ac2 again,
no problems seen.

Rebuilt 2.4.19-pre1-ac2 in 2.4.19-pre1-ac2. Reboot.

Ran the following twice.

for i in $(seq 1 10)
do 
 bzcat /net/tw/home/jrh/dl/patch-2.4.19-pre1-ac2.bz2 | patch -p1 -R
 bzcat /net/tw/home/jrh/dl/patch-2.4.19-pre1.bz2 | patch -p1 -R
 sleep 1
 bzcat /net/tw/home/jrh/dl/patch-2.4.19-pre1.bz2 | patch -p1  
 bzcat /net/tw/home/jrh/dl/patch-2.4.19-pre1-ac2.bz2 | patch -p1 
 echo "===========>" Step $i 
done

No problems seen. ac1 would have not have survived the above, so I'm
pretty sure that 2.4.19-pre1-ac2 has fixed the pre1 problems.

See the other mail for the questions - and reply to that too if you can. 
Right now I've not managed to reproduce it. Do you see the problem on

For the pre1-ac1 problems I reported, 2.95.4 (the Debian one),
reisferfs on IDE, no highmem. The tree has been patched ('official 2.4pre/rc
+ ac only) for many versions.

Now reverted to a clean 2.4.18 (full tarball) +pre1 after the disk
hard-locked in the middle patching, requiring a power cycle.  

I'm currently repeating the tests on pre1-ac2, __initial__ indications
are that the problem does NOT happen, so maybe it was the shm.

With 19-pre1-ac1 on a reiserfs partition I cannot patch a kernel. Patch
fails with "Invalid cross-device link" or "Out of disk space".

The partition has around 350 Mb free space (and has plenty of inodes
because it held linux sources + jboss + other sources that I removed).

How to reproduce:
   bunzip2 -c linux-2.4.17.tar.bz2 | tar xf -
   bunzip2 -c patch-2.4.18.bz2 | patch -p0

18-rc2-ac1 works fine on the same partition.
