Subject: BUG at kernel/timer.c:1100 when using JFFS2
Date: Wed, 21 Nov 2012 18:37:37 +1100 [thread overview]
Message-ID: <1353483457.9160.26.camel@laptop> (raw)
Hi,
I've come across a problem when loading a module straight after unmounting a JFFS2 partition.
I'm using a Geos ADSL router board with an AMD Geode LX/CS5536 chipset and a Hynix H27U1G8F2BTR NAND flash.
I can reproduce my problem with this shell script:
#!/bin/sh
mount -t jffs2 mtd:logs /mnt
echo "Hello World" > /mnt/file
umount /mnt
modprobe r8169
After a few seconds I get this panic:
kernel BUG at kernel/timer.c:1100!

Any ideas on what I should do next?
