Subject: Kernel BUG at fs/mpage.c:489

Hello,

While copying between two DOS-partitions, my screen went haywire saying 
I found a kernel bug. Since no hits on google when searching for
  kernel BUG at fs/mpage.c:489!
I decided to let you know.


Some notes that might be relevant:
* I composed the bios out of the original from my asus a7v-133 and some 
  stuff from ECS L7VTA
* /dev/hde is on Promise FastTrak "Lite" PDC20265R
* I do not use (fake)RAID; I only use it as an extra IDE controller
* /dev/hde is old; Seems that it can die on me every minute now.
* I have no historical data :-(. This computer saw its first Linux only 
  a week ago.
* /dev/hda is brand new; only a week old. Not second hand.
* /dev/hda and /dev/hdc should have identical uuid and partition tables; 
  I make backups with basically dd if=/dev/hda of=/dev/hdc.
* I retried the command, but I was unable to reproduce the problem. Only 
  thing I found after three successful copies:

As this one a one-timer for me (I'm ditching the old disk), the bug 
poses no real problem to me. But a bug is a bug nevertheless.


Happy hunting,
