2.4.24: "__alloc_pages: 0-order allocation failed"

[Daniel Brahneborg]

I wanted to test software raid, but since I've run out of physical
partitions I created two loopback devices on two ext3 partitions,
each one 2 GB. I used mdadm 1.5.0 to create a RAID1 disk, and made
an ext2 fs on it. While copying a 700MB file to it, the following
appeared in the kernel log. Checksumming the copied file gave a
different value than the original file, and checksumming it again
gave a third value.

Feb 13 20:31:18 nettis kernel: __alloc_pages: 0-order allocation failed

Feb 13 20:31:55 nettis kernel: ENOMEM in journal_alloc_journal_head,
retrying.

I'm using kernel 2.4.24, on an AMD Duron 1.3GHz with 256 MB memory
and 256 MB swap. I've run memtest86 3.0 for a day on the machine
without problems.

I searched in the archives, but could only find something that was
supposed to be fixed in 2.4.10.  I've attached my .config.

Thanks,
