Subject: [2.6.30-rc1] device-mapper: table: 254:0: crypt: Error allocating 
	crypto tfm

Kernel 2.6.30.1

I try mount encrypted partition:
root@...m:/home/maciek# cryptsetup create secret /dev/sda6
Enter passphrase:
Command failed: device-mapper: reload ioctl failed: Zły argument

"Zły argument"="Bad argument"

Dmesg shows:
[  193.421463] device-mapper: table: 254:0: crypt: Error allocating crypto tfm
[  193.421471] device-mapper: ioctl: error adding target to table
[  193.465318] device-mapper: ioctl: device doesn't appear to be in
the dev hash table

BUT, I try again:
root@...m:/home/maciek# cryptsetup create secret /dev/sda6
Enter passphrase:
root@...m:/home/maciek# mount /mnt/sec/
root@...m:/home/maciek# df -h | grep sec
/dev/mapper/secret     89G   42G   43G  50% /mnt/sec

Then it works.

root@...m:/home/maciek# cat /proc/crypto
