disk encryption causing kernel panic

Hi folks,

I'm unable to boot my previously stable workstation after attempting to install rinetd through systemd. Although rinetd worked fine prior to systemd it doesn't work now and caused /var to saturate (10Gb). This may or may not be related, but I mention it as prologue. I have access to the system via a rescue key.

The problem seems to be that there is a bug in cryptsetup? which causes 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) but get the following (condensed) output below.

I'm hoping someone has seen this before and knows a workaround. I'd rather not do a complete reinstall if I don't have to. What would I do if there were a lot of files?

Thanks much,



Please unlock disk md2_crypt:
cryptsetup (md2_crypt): set up successfully
Please enter passphrase for disk md8_crypt on /text!
