Re: disk encryption causing kernel panic

The problem seems to be that there is a bug in cryptsetup? which causes
a kernel panic.
AFAIK bugs in userland programs don't cause kernel panics. Kernel bugs
do. Userland programs may only trigger kernel bugs which cause a kernel
panic.
In the output below, md2 is (encrypted) swap and md8 is
/text - an encrypted partition. /text currently has only a few files
which I could sacrifice, although I'd rather not.
I successfully enter the password for md2 and then don't even see the
request for md8_crypt (ie a prompt for input)
Please unlock disk md2_crypt:
cryptsetup (md2_crypt): set up successfully
Please enter passphrase for disk md8_crypt on /text!
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
What then is this ?

As Reco wrote, the panic seems to be related with the swap, which was
unlocked just before the panic. Did you try to :
- not unlock md2_crypt but only md8_crypt
- unlock md2_crypt but not activate the swap within
You can use a live system or the Debian installer in rescue mode to do
the tests.
What would I do if there were a lot of files?
Restore from backup, as usual.
