Hello,


I'm running a small server with amd64 3.0-RC5 (dmesg output below).  When 
the system ist getting heavy load (e.g. heavy nfs load + 2 local makes) it 
crashes.  When load ist low, everything works fine.

I had the same problems with 2.0.3 branch too...

In most cases there is the following message on the screen:


----%<--------
fatal protection fault in supervisor mode

trap type 4 code 0 rip ffffffff803aa602 cs 8 rflags 10286 cd2 97c000 cpl 0 
rsp ffff80001278eb60
----%<--------


I'm new here and have no clue, where to continue to dig.  Maybe anybody 
can give me a hint :)


I'm not sure, if it is related with this problem:  the third hard disk has 
sometimes problems and get's downgraded to Ultra-DMA mode 3 (or even 2). 
but it always says "soft error (corrected)".

Below now the dmesg output,  thanx in advance for any answer :)
