21rc6 serverworks IDE blows even more than is usual :)

[Tomas Szepe <szepe@pinerecords.com>]

Hi Alan, Bartolomiej, Marcelo,

I can't seem to get the onboard Serverworks CSB5 IDE controller (rev 93)
in a Compaq Proliant ML350 G3 to work (reliably/at all) no matter what
kernel I use:

o  2.4.21-rc6
	intrerrupt timeouts, can't r/w from/to drive reliably in pio, dma hosed

o  2.4.21-rc2-ac3
	r/w in pio ok, dma hosed

o  2.4.20
	intrerrupt timeouts, can't r/w from/to drive reliably in pio, dma hosed

o  2.4.20-pre8-ac3 (has always worked on OSB4 beasts for me)
	intrerrupt timeouts, can't r/w from/to drive reliably in pio, dma hosed

lspci & .config excerpts plus other bits of info follow.
The box is SMP + highmem.
