The subject says everything, while detecting the drive i got the following strange thing: [from dmesg] >PIIX4: chipset revision 1 >PIIX4: not 100% native mode: will probe irqs later > ide0: BM-DMA at 0xf000-0xf007, BIOS settings: hda:DMA, hdb:pio > ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:DMA, hdd:pio >HPT366: onboard version of chipset, pin1=1 pin2=2 >HPT366: IDE controller on PCI bus 00 dev 98 >HPT366: chipset revision 1 >HPT366: not 100% native mode: will probe irqs later > ide2: BM-DMA at 0xd400-0xd407, BIOS settings: hde:pio, hdf:pio >HPT366: IDE controller on PCI bus 00 dev 99 >HPT366: chipset revision 1 >HPT366: not 100% native mode: will probe irqs later > ide3: BM-DMA at 0xe000-0xe007, BIOS settings: hdg:pio, hdh:pio >hda: IBM-DPTA-372050, ATA DISK drive >hdc: IDE/ATAPI CD-ROM 50XS, ATAPI CDROM drive >hde: , ATAPI CDROM drive ^^^^ no name here >ide2: reset >ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 >ide1 at 0x170-0x177,0x376 on irq 15 >ide2 at 0xcc00-0xcc07,0xd002 on irq 11 >hda: 40088160 sectors (20525 MB) w/1961KiB Cache, CHS=2495/255/63, UDMA(33) >hdc: ATAPI 11X CD-ROM drive, 128kB Cache, UDMA(33) >Uniform CD-ROM driver Revision: 3.11 >hde: ATAPI 8X CD-ROM CD-R drive, 512kB Cache, DMA ^^^^^ suddenly got one I've done some inquiries with hdparm: [root@Djinn dea]# hdparm -i /dev/hde /dev/hde: Model=, FwRev=, SerialNo= Config={ SpinMotCtl Removeable DTR<=5Mbs DTR>10Mbs nonMagnetic } RawCHS=0/0/0, TrkSize=0, SectSize=0, ECCbytes=8224 BuffType=8224(?), BuffSize=4112kB, MaxMultSect=32, MultSect=off DblWordIO=no, maxPIO=32(?), DMA=no (maybe): [root@Djinn dea]# hdparm -I /dev/hde /dev/hde: Model=RC2-08T1 E , FwRev=.101 , SerialNo= Config={ SpinMotCtl Removeable DTR<=5Mbs DTR>10Mbs nonMagnetic } RawCHS=0/0/0, TrkSize=0, SectSize=0, ECCbytes=0 BuffType=2(DualPort), BuffSize=0kB, MaxMultSect=0 DblWordIO=no, maxPIO=3(eide), DMA=yes, maxDMA=1(medium) (maybe): CurCHS=0/0/0, CurSects=0, LBA=yes, LBAsects=0 tDMA={min:150,rec:230}, DMA modes: ***sword2 **mword1 IORDY=on/off, tPIO={min:180,w/IORDY:180}, PIO modes: mode3 When these were performed i got this in logs: VFS: Disk change detected on device ide2(33,0) ATAPI device hde: Error: Not ready -- (Sense key=0x02) (reserved error code) -- (asc=0x3a, ascq=0x01) The failed "Read Table of Contents" packet command was: "43 02 00 00 00 00 00 00 04 00 00 00 " VFS: Disk change detected on device ide2(33,0) ATAPI device hde: Error: Not ready -- (Sense key=0x02) (reserved error code) -- (asc=0x3a, ascq=0x01) The failed "Read Table of Contents" packet command was: "43 02 00 00 00 00 00 00 04 00 00 00 " Please note the "Disk change detected": i haven't touch the drive between the two hdparm. When i attempt to mount the drive, the whole system got stuck with nothing in logs(even on serial console). I've tried different configurations(multimode on/off, reset ide2 on start, etc..) the result is always the same: lockup when mounting and garbage in logs when hdparm. Feel free to ask for more tests or for my whole .config. -- %--IRIN->-Institut-de-Recherche-en-Informatique-de-Nantes-----------------% % FORT David, % % 7 avenue de la morvandière 0240726275 % % 44470 Thouare, France [EMAIL PROTECTED] % % ICU:54999224 AIM: enlighted popo [EMAIL PROTECTED] % %--LINUX-HTTPD-PIOGENE----------------------------------------------------% % -datamining | .~. % % -networking | /V\ L I N U X % % -opensource | // \\ >Fear the Penguin< % % -GNOME/enlightenment/GIMP | /( )\ % % feel enlighted.... | ^^-^^ % %-------------------------------------------------------------------------% - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
