I am. This sounds suspiciously like the bug I reported.

But you haven't given quite enough information for me to compare. Can
you send:

1) Exact Mother board (Tyan what? Tiger MPX 2466N . . . ?)
2) Do you have DMA turned on for your IDE drives?
3) Are you enabling the AMD chip support for IDE?

. . . and anything else you can find out about the box?

Most importantly . . . does the problem go away if you turn off DMA
support for IDE?

Thanks,
