Hi,
With current git (+ kmemcheck, see below) patches I get the following
during boot:
BUG: unable to handle kernel paging request at 00001108
IP: [<c04effcf>] ext3_sync_fs+0x3f/+x80
I inserted some printks in ext3_sync_fs():
printk(KERN_EMERG "sb = %p\n", sb);
printk(KERN_EMERG "sb->s_fs_info = %p\n", sb->s_fs_info);
And they show:
sb = f7f61e00
sb->s_fs_info = 00000000
Monitorshot: http://folk.uio.no/vegardno/linux/DSCF2905.JPG
Config: http://folk.uio.no/vegardno/linux/config-20080501.txt
I am booting a USB stick with an ext2 filesystem as root partition. It
mounts fine in other machines.
It could of course be my kmemcheck patches that are causing this
(though I find it unlikely as they are disabled on boot => no-op, and
everything was fine a couple of days ago), but recompiling this config
takes a few hours, and I thought I'd just post early in case the
problem is really with ext3.
I can send vmlinux image and/or disk image if necessary.
Thanks.

Looks like a bug introduced by quota change - it should be fixed in
the current Linus's kernel. Thanks for report anyway.
