To: Linuxppc-dev Subject: SCSI system freeze w/2.4.18 Message-ID: <20020404195209.GG30247@regulus> Mime-Version: 1.0 Content-Type: text/plain; format=flowed; charset=ISO-8859-15 Sender: owner-linuxppc-dev@lists.linuxppc.org List-Id: [I already posted this to the users list, but apparently nobody had a solution...] I upgraded my PowerMac 7300 from 2.4.6-pre3 to (stock) 2.4.18, and since then I have a nasty scsi problem: Trying to read data from the cd drive without a cd loaded (e.g. "dd if=/dev/scd0 of=/dev/null bs=1 count=1") freezes the machine. I usually use this command in a shutdown script to detect and eventually eject a floppy and a cd. This worked perfectly before, but hangs without *any* notice in the logs in 2.4.18. I am almost sure that this is a SCSI problem, as the same script works still nicely on an iMac (which has a ide cd drive) with 2.4.18. System details are-- PowerMac 7300/166, CD attached to internal scsi bus (MESH), verbose scsi logging enabled, mesh compiled into the kernel, LinuxPPC 2000, upgraded to Halloween release, kernel 2.4.18 from kernel.org, plus post-release elf patch, built with gcc-2.95.2, glibc 2.1.3 Thanks in advance for any help, Albrecht. -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Albrecht Dreß - Johanna-Kirchner-Straße 13 - D-53123 Bonn (Germany) Phone (+49) 228 6199571 - mailto:albrecht.dress@arcor.de _________________________________________________________________________ ** Sent via the linuxppc-dev mail list.
