following from Syslog ..
Any Ideas what is going on?
Thanks ...

Ok, first IANAKP (I am not a kernel programmer ) ;-> ...
But, just got another hard lockup and EIP code ...
I am not sure why this should got to nVidia (Please, I
personally know the Head of nVidias' Linux driver development,
so if it is a nVidia problem, I can help there).
Anway,
EIP shows :
desktop kernel: CPU: 0

c01ba6aa T radix_tree_tag_set
c01ba74c T radix_tree_tag_clear
c01ba81a t __lookup
c01ba906 T radix_tree_gang_lookup
The "radix lookup" seems to be occuring inside of the radix_tree_tag_set
and in particular the pdflush routine.
fgrep'ing kernel shows this is in the lib/radix-tree routine ..
To me seems to be a PDFLUSH eip and the nvidia stuff is just
a by product of loaded modules, no?
Thnaks ..

Maybe is, maybe isn't.

The point is that we can't know that the NVidia module hasn't stomped on
some random memory location that happened to corrupt a radix tree. Note
that this is true even if you've loaded and then unloaded the module - it
may have splatted something before it departed....
Is it a replicatable error, and if so, can you replicate it without loading
the NVidia module? If you can come up with a traceback that doesn't have
an NVidia tainting in it, we'll be glad to look at it. Conversely, if you're
able to replicate it with nvidia loaded, but not without, toss it over
the fence to your friend.
Ok, I can remove the module so it no longer is loaded ..
It is replicate able, but randomly. Seems to occur when I hammer on
the SATA drive in the system, which is running on a add-on SIL 3112a
controller card.
Anyway, driver is removed, system rebooted, ksyms logged.
I will hammer again on the system to see if it fails ...
Thanks ...

Ok, Same stuff, different day. Took the nVidia drivers out.
Ran HOT MEM checks, all passed (elimnating RAM issues).
Same as this time last month.
Got hard lock ups every 2 - 3 days. No syslog / debug ever given -
pdflush ,when top is left running on console - shows 100% CPU usage.
FINALLY got this morning a EIP error :
