Package: linux-image-2.6.14-1-686 Version: 2.6.14-2 Severity: important I have 2.6.12 and 2.6.14 (686 P4) installed on this machine. If I boot back into 2.6.12 DMA is on for /dev/hda. It is off in 2.6.14 and will not enable:
# hdparm -d 1 /dev/hda /dev/hda: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off) This has, as you can imagine, very detrimental effects with ext3 filesystem responsiveness. Ugh! DMA has worked in every kernel image I have used with this machine, tracking Sid since summer 2003 with 2.4 and 2.6 kernels. Until now, that is. Please let me know what other information you might need. Here is a hdparm -i just in case that helps. /dev/hda: Model=HITACHI_DK23EA-60, FwRev=00K2A0A3, SerialNo=DZ4767 Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs } RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=4 BuffType=DualPortCache, BuffSize=2048kB, MaxMultSect=16, MultSect=16 CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=117210240 IORDY=yes, tPIO={min:240,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio1 pio2 pio3 pio4 DMA modes: mdma0 mdma1 mdma2 UDMA modes: udma0 udma1 udma2 udma3 udma4 *udma5 AdvancedPM=yes: mode=0x80 (128) WriteCache=enabled Drive conforms to: ATA/ATAPI-5 T13 1321D revision 3: -- System Information: Debian Release: testing/unstable APT prefers unstable APT policy: (500, 'unstable') Architecture: i386 (i686) Shell: /bin/sh linked to /bin/bash Kernel: Linux 2.6.14-1-686 Locale: LANG=en_US, LC_CTYPE=en_US (charmap=ISO-8859-1) Versions of packages linux-image-2.6.14-1-686 depends on: ii module-init-tools 3.2-pre9-4 tools for managing Linux kernel mo ii yaird [linux-initramfs-tool] 0.0.11-12 Yet Another mkInitRD linux-image-2.6.14-1-686 recommends no packages. -- no debconf information -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
