Default Repeated Raid1 Failures after upgrade to Lenny

So I upgraded to Lenny over the weekend, and now I'm having issues with my RAID1 were there weren't any before. Every few hours one of the devices making up any /dev/md will fail. It's usually on /dev/sdb but it's happening on /dev/sda as well. I can set the device faulty in mdadm and then readd and it builds fine, but then fails again 4 or 5 hours later. I'm new to Linux software RAID so i'm hoping someone can point me in the right direction.


Here's some of the output from dmesg:

Do you still have Etch's kernel installed?
Boot from that and see if it continues?

<erno> hm. I've lost a machine.. literally _lost_. it responds to
ping, it works completely, I just can't figure out where in my
apartment it is.

This looks like a hardware problem, not a software problem. It's
probably just your disk breaking, but it could the the SATA
controller too.

Install smartmontools and see the output of

smartctl -d ata -H -l error /dev/sdb
