[parisc-linux] D380 and ext[23] fs grave pb

[Joel Soete]

Hello *pa,

Making some stress test to atempt to identify some smp pb on my d380, I figure
out this ext[23] relatively grave pb. Effectively during this test loop:
# while true ; do nice -n -3 tar -xspf linux-2.6.11-rc3-pa3.tar ; nice -n -3 rm
-rf linux-2.6.11-rc3-pa3 ; date ; done

after about 30 iteration, I got a fs' corruption:
EXT3-fs error (device sda10): ext3_readdir: bad entry in directory #84801:
rec_len % 4 != 0 - offset=0, inode=175234
Aborting journal on device sda10.

ext3_abort called.

EXT3-fs error (device sda10): ext3_journal_start_sb: Detected aborted journal

Remounting filesystem read-only

EXT3-fs error (device sda10): ext3_readdir: bad entry in directory #84801:
rec_len % 4 != 0 - offset=0, inode=1752397164, rec_len=24
EXT3-fs error (device sda10): ext3_readdir: bad entry in directory #84801:
rec_len % 4 != 0 - offset=0, inode=1752397164, rec_len=24
[snip]

and during fsck I noticed:
__journal_remove_journal_head: freeing b_committed_data

Pass 2: Checking directory structure
Directory inode 84801, block 0, offset 0: directory corrupted
Salvage? yes

Missing '.' in directory inode 84801.
Fix? yes

Setting filetype for entry '.' in ??? (84801) to 2.
Missing '..' in directory inode 84801.
Fix? yes

As the first time it was with a smp kernel, I re-test with up kernels only.

This pb occured with different (up) kernels (2.6.17-rc6, 2.6.14, 2.6.17 and
even with 2.6.8.1) on different fs located on different disk and different
hba, and finaly on the 2 different cpu?

That said I also get a fs corruption during a simple apt-get dist-upgrade:
(sdb6 being /var)

It's the only system of this model on which I can reproduce but also I can
test (and as I am not hp, I don't have passwd diagnostic cd to test hw ;-( ),
so it's very hard to me if it's a driver pb (e.g. ncr hba) or a hw pb?

Any idea, advises are welcome.

Thanks in advance,
