I also can not see this bug on regression.

Close it.

--- Vivi Li 2010-03-18 23:32:03

I see this bug again on 2010_Feb_27 and 2010_Mar_16 in trunk.

--- Sonic Zhang 2010-07-12 06:27:11

fail to replicate on uClinux-dist rev. 9681 and kernel rev. 8927

--- Robin Getz 2010-07-12 08:26:37

Sonic:

Can you put things (in the shell's) "while [ 1 ] ; do bonnie++ -u root -d

/mnt/hd2 ; done" - ping flood it from your host (to create lots of kernel

interrupts), and let it run over night?

Just be because it runs once doesn't mean there isn't a problem there... If it

can run 16+ hours without a crash, during a ping flood - it normally means it's

pretty stable.

--- Sonic Zhang 2010-07-13 01:43:30

I have already run it more than 1 hour. Not see the crash.

If 16+ hour is preferred, no problem.

--- Vivi Li 2011-11-02 05:22:26

I see this again in 2011r1 branch after test script is modify for out of memory

problem.

Run bellow command to reproduce:

root:/> while [ 1 ] ; do mke2fs /dev/sda2; sleep 3; mount /dev/sda2 /mnt;

sleep 3; time bonnie++ -u root -d /mnt -s 200M; done

--- Sonic Zhang 2011-11-04 04:56:53

This bug can be replicated only on large disk size, such as 20G /dev/sda2.

--- Sonic Zhang 2011-11-04 06:35:44

If reducing the file size of bonnie++ from 200M to 100M, this bug disappear even

on 20G /dev/sda2.

--- Sonic Zhang 2011-11-07 05:10:57

If limiting bonnie++ file size to 50M, this bug disappears even on 20G /dev/sda2

--- Sonic Zhang 2012-01-12 03:11:28

This bug disappears after update to kernel 3.2.0.

while [ 1 ] ; do mke2fs /dev/sda2; sleep 3; mount /dev/sda2 /mnt; time

bonnie\+\+ -u root -d /mnt -s 100M; umount /mnt; done
