The device: http://storcase.com/dataexpress/de110.asp It has always worked fine with any kernel up to and including 2.6.6. Starting with 2.6.7 (both vanilla and Gentoo patched), it does not work. In fact, trying to access any file on the drive, renders the entire disk I/O system unusable (entering any command that requires access to the fixed hard drive from a console doesn't execute and never returns). The machine has an Intel 6300ESB SATA Storage Controller (I have "Intel PIIX/ICH SATA support" enabled in the kernel). The main hard drive (Seagate SATA) appears to works fine. I can mount the filesystem on the drive in the carrier without any problems, but as soon as I try to read from or write to that drive, the applications lock up as soon as they access the hard drive. Eventually, I can't do anything, and have to reboot the system. The manufacturer claims it knows of no incompatibilities, and tells me that a lot of people had problems starting with 2.6.7. I had heard that 2.6.7 brought a lot of changes to the SATA stuff, and I hoped that this would get fixed soon, but the problem still exists in Gentoo 2.6.10-r4. I still keep a 2.6.6 kernel around to dual boot with when I have to access the drive, but this represents a large pain in the you know what (and all of the 2.6.6 ebuilds have now disappeared from portage). Reproducible: Always Steps to Reproduce: 1. mount /dev/sdb1 /mnt/disk 2. cp /mnt/disk/file /path/to/anywhere Actual Results: Maybe a small amount gets copied (about 300k). After that the console locks up with recovery impossible. Expected Results: Drive should work as it did pre-2.6.7. $ emerge -p info Portage 2.0.51-r3 (default-linux/x86/2004.2, gcc-3.3.5, glibc-2.3.4.20040808-r1, 2.6. 10-gentoo-r4 i686) ================================================================= System uname: 2.6.10-gentoo-r4 i686 Intel(R) Pentium(R) 4 CPU 3.00GHz Gentoo Base System version 1.4.16 Autoconf: sys-devel/autoconf-2.59-r5 Automake: sys-devel/automake-1.8.5-r1 Binutils: sys-devel/binutils-2.15.92.0.2-r1 Headers: sys-kernel/linux26-headers-2.6.8.1-r2 Libtools: sys-devel/libtool-1.5.2-r7 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CFLAGS="-march=pentium4 -O3 -pipe -fomit-frame-pointer -msse2 -mfpmath=sse" CHOST="i686-pc-linux-gnu" COMPILER="" CONFIG_PROTECT="/etc /usr/X11R6/lib/X11/xkb /usr/kde/2/share/config /usr/kde/3.3/env /usr/kde/3.3/share/config /usr/kde/3.3/shutdown /usr/kde/3/share/config /usr/share/ config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-O2 -mcpu=i686 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs autoconfig ccache distlocks sandbox sfperms" GENTOO_MIRRORS="http://gentoo.osuosl.org http://distro.ibiblio.org/pub/Linux/ distributions/gentoo" MAKEOPTS="-j3" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="X aalib acpi alsa apache2 arts avi berkdb bitmap-fonts caps cdparanoia cdr crypt cups dga directfb divx4linux dvd dvdr encode f77 faad fam fbcon flac font-server gd ggi gif gmp gphoto2 gpm gtk2 idea imagemagick imap imlib ipv6 javascript jikes joystick jpeg kde lcms libg++ libwww live mad matroska mbox memlimit mmx mmx2 mpeg mpi mysql nas ncurses network nls nptl oggvorbis opengl pam pdflib perl png qt quicktime readline rtc samba scanner sdl silc speex spell sse sse2 ssl svga tcpd theora tiff truetype truetype-fonts type1-fonts unicode usb vanilla wifi x86 xinerama xml2 xmms xv xvid zlib linguas_en linguas_ru"
does this problem still occur with 2.6.11_rc1 (-mm1?)
Created attachment 48620 [details] .config
Do you mean these sources? /usr/portage/sys-kernel/mm-sources/mm-sources-2.6.11_rc1-r1.ebuild I installed them, and compiled the kernel, and the problem still exists (no change at all).
Then please file a bug for this at http://bugzilla.kernel.org as it is not related to gentoo kernels.
