Hi, I have a MSI KT4 Ultra MoBo with KT400 and VT8235 , before of this I
had an Apollo PRO 133 and all worked fine, with this mobo there isn't
DMA support for my southbridge in kernel 2.4.19 , so I've upgraded it to
2.4.20 , but I have a problem.
In the boot I see that he recognize my chip and turn on DMA on hda and
hdb (My HD) , but when it try to start DMA on my hdc (first DVD Reader)
It locks up with "hdc: DMA disabled" message, then it said about the
device that is BUSY , then it said "ide1: resetting!" and return to the
message above ("hdc:DMA...:") in an infinite loop.I don't know what to
do.I've tried to install ac2 patch for linux-2.4.20 tree, and it don't
lock up to hdc: DMA disabled (this appears again , but don't freeze
here) but when I try to enable ide-scsi module it freeze with messages
about SCSI problems, then it tries to resetting all the SCSI emulated
devices and this create an infinite loop of these messages!
What is the problem?
Thanks a lot
Bye
Marcello
