PROBLEM: Kernel lockup on alpha with heavy IO

[Dru]

I've recently installed debian on a alpha box and have a problem with  
the kernel locking up
after a couple of hours of heavy use.  An individual partition will stop 
responding, all processes
that try and access it will just sit there waiting and you have to 
reboot the server.
I've been using a mixture of IDE drives and they all do this. I thought 
it might be the motherboard
so i've installed a pci ide controller card, had same effect. I've tried 
accessing files over usb devices
as a finial ditch effort but it also does it there also so i am sure it 
is in the kernel and not
the hardware that is at fault.

Kernels I've tried.
Linux 2.6.5, Linux 2.4.18

To re-create the problem on an alpha, copy directories around from one 
partition to another. Have
several copies going at once, do a few hdparm -t -T as well and 
generally provides a lock up within
an hour.  I am running a mixture of ext3 and xfs for partitions.
