Fedora Kernel: soft lockup ever resolved?

My Fedora 9 machine is locking up pretty daily (well the X server does). It does very frequently generate "soft lockup" kernel oops's.

Nov 4 13:18:13 localhost kernel: BUG: soft lockup - CPU#2 stuck for 122s! [ksoftirqd/2:10]
Nov 4 13:18:13 localhost kernel: BUG: soft lockup - CPU#0 stuck for 122s! [FahCore_a1.exe:25966]
Nov 4 13:18:13 localhost kernel: BUG: soft lockup - CPU#3 stuck for 122s! [rsyslogd:2474]
Nov 6 02:50:12 localhost kernel: BUG: soft lockup - CPU#3 stuck for 498s! [ksoftirqd/3:13]
Nov 6 02:50:12 localhost kernel: BUG: soft lockup - CPU#2 stuck for 498s! [FahCore_a1.exe:3605]

As you see I'm folding at home, so the machine runs on high load. But apart from having the propitiatory NVIDIA drives and a soft mirror it's pretty much a bog standard Dell Inspiron 530. It started a few months back with one of the kernel upgrades.

I see from the kerneloops.org that this is a common error, second most common on 2.6.26-release. But virtually all the instances are on fc9 kernels. And this error (I'm presuming) still seems to be in the Fedora 10 as all the entries for this error on 2.6.27-release are fc10 kernels.

So is the error a bug in Fedora kernels over and above the upstream/other vendors, or well known issue that I need to address in my setup.

Sorry to ask about this again if well known, but searching around has given me no real information on what this might be.

Thanks
