There are lots of reports and stack dumps at https://bugzilla.redhat.com/show_bug.cgi?id=538920 . It seems it's mainly a communication issue to get those dumps on lkml where people can look at it. It's still happening with 2.6.31.11 and people report in that bug tons of versions and stack traces. I'm mostly clueless when it comes to kernel debugging but if you can help please take a look. Thanks!

I have no problems on anything 2.6.30-rc6 and beyond, but others have had some issues with infinite loops in the driver that I don't think were ever fully resolved. However, that doesn't sound like your problem. It's unclear what kernels you've tried. You seem to imply that you've tried kernels since 2.6.29, but what's the latest kernel you've tried and had the issue with? It will also help if you either send your dmesg output or dmesg | egrep '(XID|^Linux version)' so that we can see more details about the hardware. Dave
