Also if this problem happens only after a cold boot, but a warm boot is valid, you can set the CONFIG_IDEDMA_IVB=y Regards, On 17 Jan 2002, Arkadiusz Miskiewicz wrote: > > Hi, > > I'm using 2.4.17 with ide.2.4.16.12102001.patch.bz2 + other > patches (listed here: http://cvs.pld.org.pl/SPECS/kernel.spec?rev=1.70.2.390) > on FIC LX based (quite old) mainboard + external PCI controller: > > 00:07.1 IDE interface: Intel Corp. 82371AB PIIX4 IDE (rev 01) > 00:08.0 Unknown mass storage controller: Promise Technology, Inc. 20268 (rev 01) > > My IDE setup is fully modular (well, whole kernel is): > xfs 479200 4 (autoclean) > xfs_support 6216 0 (autoclean) [xfs] > pagebuf 22112 4 (autoclean) [xfs xfs_support] > nls_iso8859-1 2880 1 (autoclean) > nls_cp437 4384 1 (autoclean) > vfat 9788 1 (autoclean) > fat 30680 0 (autoclean) [vfat] > sr_mod 13656 0 (autoclean) (unused) > scsi_mod 86776 1 (autoclean) [sr_mod] > ide-cd 27552 0 > cdrom 28320 0 [sr_mod ide-cd] > ext3 58772 1 (autoclean) > ide-disk 9712 8 (autoclean) > ide-mod 153756 8 (autoclean) [ide-cd ide-disk] > jbd 34424 1 (autoclean) [ext3] > > Kernel boots fine: > Linux version 2.4.17 (builder@kenny) (gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)) #1 Tue Jan 15 13:19:47 UTC 2002 > ... > Freeing initrd memory: 174k freed > VFS: Mounted root (romfs filesystem) readonly. > Journalled Block Device driver loaded > Uniform Multi-Platform E-IDE driver Revision: 6.31 > ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx > PIIX4: IDE controller on PCI bus 00 dev 39 > PIIX4: chipset revision 1 > PIIX4: not 100% native mode: will probe irqs later > ide0: BM-DMA at 0xf000-0xf007, BIOS settings: hda:pio, hdb:pio > ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:pio, hdd:pio > PDC20268: IDE controller on PCI bus 00 dev 40 > PCI: Found IRQ 11 for device 00:08.0 > PDC20268: chipset revision 1 > PDC20268: not 100% native mode: will probe irqs later > PDC20268: ROM enabled at 0xea000000 > ide2: BM-DMA at 0xe400-0xe407, BIOS settings: hde:pio, hdf:pio > ide3: BM-DMA at 0xe408-0xe40f, BIOS settings: hdg:pio, hdh:pio > hda: ASUS CD-S500/A, ATAPI CD/DVD-ROM drive > hde: IBM-DTLA-307030, ATA DISK drive > hdf: IBM-DTLA-305040, ATA DISK drive > hdh: ST360021A, ATA DISK drive > ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 > ide2 at 0xd400-0xd407,0xd802 on irq 11 > ide3 at 0xdc00-0xdc07,0xe002 on irq 11 > hde: 60036480 sectors (30739 MB) w/1916KiB Cache, CHS=59560/16/63, UDMA(33) > hdf: 80418240 sectors (41174 MB) w/380KiB Cache, CHS=79780/16/63, UDMA(33) > hdh: 117231408 sectors (60022 MB) w/2048KiB Cache, CHS=116301/16/63, UDMA(33) > Partition check: > /dev/ide/host2/bus0/target0/lun0: p1 p2 p3 p4 < p5 p6 > > /dev/ide/host2/bus0/target1/lun0: p1 p2 > /dev/ide/host2/bus1/target1/lun0: p1 > kjournald starting.
