Sibert" User-Agent: Mozilla/5.0 (X11; U; Linux 2.4.1-pre8 i686; en-US; m18) Gecko/20010116 X-Accept-Language: en MIME-Version: 1.0 To: linux-kernel@vger.kernel.org Subject: oops in 2.4.1-pre8 Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hello. I've got a Dell Precision 420 (dual P3/800 w/1gb RDRAM). I'm consistently getting an oops when accessing any smbfs mount whether running 'ls' inside the smbfs mount or hitting TAB for filename completion of a directory in an smbfs mount. I have another machine (dual P2/300 w/320MB memory) that does not have this problem. The P2 has an eepro100 ethernet card whereas the Dell has the built-in 3c920 (3c905c emulation). Below is the ksymoops output. The oops screen I manually typed onto my other computer because the /var/log/messages file gets corrupted when this occurs and I don't know how to save the oops screen on the computer itself. SAR-S, SAR-U say they're doing to do their action but do not actually sync or remount the disks. CAD does not reboot the computer. SAR-B does reboot the machine though.

I've compiled this kernel with 4GB bigmem support (otherwise I only get 8xxMB total).
