IDE DMA on 2.4.0test3-pre1 still broken?

[Laurent DUFOUR]

Hi,

I have the same problem as Andreas Franck, system hang when doing big
access to disk (in my case cp -a /usr/src/linux in another place on the
same disk/partition).
I tried this on the console, and the following message is displayed
periodically : "hda : lost interrupt".
All the system is not blocked, but each disk acess is blocked, keyboard,
mouse (via gpm) work correctly.

If you are interested, here is my configuration (kernel
2.4.0-test2-ac2):
Jun 29 11:41:20 gym1 kernel: Uniform Multi-Platform E-IDE driver
Revision: 6.31
Jun 29 11:41:20 gym1 kernel: ide: Assuming 33MHz system bus speed for

I hope this could help you.
By the way, I didn't subscripe to the mailling list because i can't load
all messages, so could you reply also to my address.

Thanks
