Kernel panic while importing a pool

I had several kernel panics, and I finally understood that one of memory was bad. I removed it. But now, each time I try to import my pool, I get a kernel panic
I'm using freebsd 9.0-release generic

Fatal trap 12: page fault while in kernel mode

dmesg :

What else can I add to help solving this bug?

I'm not very good with freebsd.
