Sender: parisc-linux-admin@lists.parisc-linux.org Errors-To: parisc-linux-admin@lists.parisc-linux.org List-Help: List-Post: List-Subscribe: , List-Id: parisc-linux developers list List-Unsubscribe: , List-Archive: PARISC'ers, I have a stable cluster of 715/50's running 2.4.9-pa25. In a recent attempt at moving to a newer kernel the following problems started to crop up... Originally 2.4.9-pa25 had to be booted with sim700=noneg:0xff,nodisc:0xff or the SCSI drives would not respond to the driver. This was understood since the driver was in development and did not support all the required features. In October a newer driver was merged into the tree... and herein possibly lies the problem. Most of my initial testing was with our 712/60 that had no issues. However the 715/50's had other ideas... --------------------------------- HD contains 0.9.3 latest install with a few apt-get upgrades. /dev/sda1 = Swap /dev/sda2 = ext2 / Box is a 715/50 (2.4.17-pa6) Searching for devices...

The nfsroot was created from the 0.9.3 install plus some apt-get upgrades. This runs great, tested a few apps (vi,top,du...), ran a tar/gzip of a few hundred megs. Then mount -o rw,remount / Followed by the startup of all daemons. /etc/init.d/rcS -> Run all /etc/rc.S stuff /etc/rc2.d -> Run it... Done. Runs amazingly. Which does lead me to assume that the 53c700 driver is having some problems with these machines. I'm all ears to suggestions, and willing to do some work to get stuff back on track :) Where do I go from here? Solid lockups are a new kind of problem for me... c.
