From: Andrew Thompson To: linux-kernel@vger.kernel.org Content-Type: text/plain Message-Id: <1058708549.13241.11.camel@vagabond> Mime-Version: 1.0 X-Mailer: Ximian Evolution 1.4.3 Date: 20 Jul 2003 14:42:29 +0100 Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org I've been playing around with the latest dev kernels and I've had a strange problem where linux locks up after about 10 minutes of use in Xfree. I first noticed this problem in 2.5.75 and I've also experienced it with 2.6 test1 and 2.6 test1-mm1 with and without the O7int patch. Basically what happens is the audio in playing starts looping, the LED that indicates disk activity stays on constantly and the computer stops responding. By removing all superfluous kernel options and gradually adding them again I've narrowed down the cause to SCSI emulation for ATAPI CD burners. I can enable basic SCSI support without a problem but if I enable the SCSI emulation, the SCSI Cd-Rom support and the generic SCSI support the kernel locks up as reported above. I haven't tried each of those options separately (crashing linux repeatedly and having to recompile the kernel the whole time is a PITA) but I'm willing to do that if anyone thinks it would be useful. My current system is an ASUS A7M266-D with 1024 megs of ram, a SB-Live card running with the OSS drivers and a Geforce 2 Ti 500 using the nvidia kernel module. If any more information is required please ask me. TIA, Andrew Thompson.
