Comment 5 for bug 155689

I met same problem on my ThinkPad T43p: Occasionally (about 2 out of 5), my Gutsy system got panic on boot. I've installed my Gutsy system using alternative CD with encrypted root partition (no encryption of swap nor /boot). The panic occurred soon after I enter the correct root partition password in the splash screen.

Steps to Reproduce:
1) Boot the system
2) Input correct encrypt filesystem password in GUI splash screen

Actual Results:
Kernel panic in about 2 out of 5 boots

Expected Results:
Always good boot

Reproducibility:
About 2 out of 5 boots.

Build Date & Platform Bug Found:
Gutsy on an i686 ThinkPad T43p with encrypted root partition. Swap nor /boot not encrypted. All updates installed (no pre-release updates)
