Hi all,

 This is somewhat offtopic; bear with me, someone may be able to help!
 I posted a short while back that I'd suffered quite a large data loss
 with mdadm and a handful of SATA disks, it looks like it was caused by
 a bug in the sata_sil driver as there is stuff posted here:
 http://www.ussg.iu.edu/hypermail/linux/kernel/0707.1/0024.html as well
 as a bug on Ubuntu's launchpad site:
 https://bugs.launchpad.net/ubuntu/+bug/208551

 I'm no kernel hacker, and I have not found much more evidence to
 support the fact it's a bug other than I can reproduce the failure
 pretty consistently (6 hard disks over 3 PCI sil 3512 based SATA
 cards). I've just ordered a new motherboard, CPU etc. for the
 fileserver in question and can test things a bit more thoroughly once
 they appear and I have time to swap out the guts of my current
 machine. Does anyone know how I'd go about even starting to help fix
 this sata_sil maybe-bug, or indeed if a fix has already been committed
 to the kernel, or at least how to help track it down?

What kernel version are you able to reproduce the problem?
