Hard Drive and Module Errors From Gentoo Kernel
 

Hey all. I recently installed Gentoo and I've got almost everything I need working. One of the issues I'm having are these strange messages during bootup. Here is the output of dmesg that is concerning me:

Partition check:
/dev/ide/host0/bus0/target0/lun0: p1 p2 p3
/dev/ide/host0/bus0/target1/lun0:hdb: timeout waiting for DMA
ide_dmaproc: chipset supported ide_dma_timeout func only: 14
hdb: status timeout: status=0xd0 { Busy }
hda: DMA disabled
hdb: drive not ready for command
ide0: reset: success
hdb: timeout waiting for DMA
ide_dmaproc: chipset supported ide_dma_timeout func only: 14
hdb: status timeout: status=0xd0 { Busy }
hdb: drive not ready for command
ide0: reset: success
p1 p2

This part takes a while to get through during bootup apparently because their is a timeout waiting for DMA on my disc. I'm baffled by this error. Is this some sort of drive failure? I should also tell you that this is my second hard drive used strictly for Gentoo. It has a boot(/dev/hdb1) and a root(/dev/hdb2) partition. The swap space is used by the existing swap partition on the first drive(/dev/hda3).

The other problem I'm having is with my cdburner. It just won't burn anything period. I noticed that their was another issue in the dmesg output that probably has to do with why my cdburner isn't working:

SCSI subsystem driver Revision: 1.00
kmod: failed to exec /sbin/modprobe -s -k scsi_hostadapter, errno = 2
kmod: failed to exec /sbin/modprobe -s -k scsi_hostadapter, errno = 2
kmod: failed to exec /sbin/modprobe -s -k scsi_hostadapter, errno = 2

So it seems that I don't have the scsI_hostadapter module installed right? Do I have to rebuild the kernel with this modules in there in order for it to work?

Thanks everybody.

do you enable dma using "hdparm -d 1 /dev/hdb"?
and about the cd burner, is it ide? (if so, have you enabled ide-scsi emulation?)

Well the "hdparm -d 1 /dev/hdb" did the trick as far as the dma errors. I thought that most bios's enable dma automatically.

I also just added the ide-scsi module and it works fine. I didn't realize that module wasn't loading.

Thanks.

I'm still having problems with the dma timeouts. It seems that sometimes when I reboot dma is turned off again. Is their anyway to permanently set dma to on?
