Attempted install of gentoo-basic-x86-1.4_rc2.iso This is on an ABIT BP6 with 2 x Celeron 400MHz. IBM Hard Disk attached (Deskstar 120GXP) hde: IC35L040AVVA07-0, ATA DISK drive kernel hangs at Partition check: /dev/ide/host2/bus0/target0/lun0: Tried booting with gentoo noapic acpi=off noscsi but this made no difference. (acpi=no as documented in the cdrom bootloader screen doesn't turn of acpi. acpi=off is needed to do this.)
To clarify, the IDE controller is a Promise Ultra 100TX2 (PDC20268)
try latest experimental livecd please , has newest ide core
I tried livecd-basic-x86-2003011400.iso. It got past the Partition check on 3 out of 4 boots. On writing partition table with fdisk I get hde: timeout waiting for DMA PDC202xx: Primary channel reset ide_dmaproc: chipset supported ide_dma_timeout func only: 16 The partition table does not get written. I've going to run the disk through IBM's Drive Fitness Test to rule out a problem with the drive, and I'll see if it works ok with DMA turned off. My gut feeling is that PDC202xx doesn't work properly yet with DMA :(
Hi DFT says disk is in good health. Everything works ok if I turn DMA off (create partitions and filesystems) ide=nodma does NOT turn off DMA on this device, although it does allow the kernel to boot. I had to turn off DMA manually with hdparm before I could safely use fdisk. I think I'll try installing gentoo with DMA turned off and then try various kernels such as -ac or 2.5. I'll complain to lkml if I don't get anywhere, so feel free to close this bug... Thanks, Nick
xfs-sources and gs-sources, maybe gentoo-sources (check changelog) Have fixes for this chipset.
