SubjectCRC32C big endian bugs...
From

The CRC32C implementation in the btrfs progs is different from the one
in the kernel, so obviously nothing can possibly work on big-endian.

This is getting less and less fun by the minute, I simply wanted to
test btrfs on Niagara :-/

Here is a patch to fix that:

--- vanilla/btrfs-progs-0.12/crc32c.c 2008-02-06 08:37:45.000000000 -0800
+++ btrfs-progs-0.12/crc32c.c 2008-02-12 01:19:33.000000000 -0800

+u32 crc32c_le(u32 crc, unsigned char const *data, size_t length)
{
- u32 crc = (__force __u32)(cpu_to_le32(seed));
-
while (length--)
crc =
crc32c_table[(crc ^ *data++) & 0xFFL] ^ (crc >> 8);

- return le32_to_cpu((__force __le32)crc);
+ return crc;
}
