Re: 2.4.0-test11 EXT2 corruption (2)

[Frank van Maarseveen]

In addition to the previous:
A clean rebuild of a linux tree failes because of EXT2 data block mixups
(?).  A second rebuild reveals further corruptions of similar nature. A
final fsck uncovers a few lost inodes. All file lengths are reasonable
i.e. no magic power of two numbers there.

Now this _is_ bizarre since these are official patches and have worked before.

cycling power revealed two things:

	still in effect.
-	BIOS reported I had only 64MB but I _did_ add 128MB two weeks ago. No

	only 64MB (I checked /var/log/messages for this).

Re: 2.4.0-test11 EXT2 corruption (3)

Hmm, not only I see files stuffed with random data but sometimes also with
a block of zeroes (about 3600 consecutive zero bytes in a .depend file)
At one time /var/log/messages said while doing rm -rf:

Dec 10 21:23:04 iapetus kernel: EXT2-fs error (device ide0(3,4)): ext2_readdir: bad entry in directory #152149: rec_len is smaller than minimal - offset=0, inode=0, rec_len=0, name_len=0

Maybe it is a hardware problem?

No, it's a test11 problem. Go to test12-pre[latest].

Rather unusual for a console driver ;-)

fsck didn't find anything.

I checked a test11 tree and it seems that only the contents of the three
files was messed up, not the mtime/length. I can't rule out a hardware
cause but this doesn't look like a typical hardware problem to me:
mixing up data of different files.

Maybe SMP related because hardware is a dual PIII-450.

I see lots of messages from you about corruption in 2.4.0-test11
but we all know very well that 2.4.0-test11 corrupts things
and further evidence is not necessary.
Hopefully all, or at least the most significant, problems
have been solved now, so you should upgrade to the most
recent test kernel and see how things are there.

Thanks. test12-pre7 fixes this for me: it ran all night testing and
no problems so far.

I'm running test12-pre7 and had a bad lockup a couple of days ago. Or
actually it wasnt a lockup it was a "klonk" in the harddrive when I
started netscape then the machine rebooted. And I had a corruption in the
$HOME/.netscape/cache directory. No logged messages or anything anywhere.
The machine just rebooted and I had to manually fsck /home.
