Good Sunday afternoon all, I've managed to crash the netra X1 fairly quickly with both latest snapshot and also with re-compiled kernel with subr_poolc patch below.
Steps: 1. netboot netra, install latest sparc64 snapshot, no customization apart from networking setup in installer and user setup. (not even enabling soft updates) 2. ping -f 192.168.3.1 # default gw, runs on serial console 3. ssh in from different PC in LAN, in /usr run: cvs -d anon...@openbsd.cs.fau.de:/cvs checkout -P src (I also had a crash where I ssh'd in and did ftp http://192.168.3.52/src.tar ~700M, crashed somewhere in half, just displaying progressbar from ftp command ...) wait a bit and bam: panic: psycho0: uncorrectable DMA error I've tried to ddb> boot crash an/or boot dump, it tries to store the crashdump, but on reboot, nothing is in /var/crash apart from minfree file: # ls -lh minfree -rw-r--r-- 1 root wheel 5B Nov 21 19:40 minfree I guess I have enough free space, the machine has 384M of RAM and swap is 640M # df -h Filesystem Size Used Avail Capacity Mounted on /dev/wd0a 492M 50.0M 418M 11% / /dev/wd0k 61.2G 1.0G 57.1G 2% /home /dev/wd0d 251M 10.0K 239M 0% /tmp /dev/wd0f 2.0G 378M 1.5G 20% /usr /dev/wd0g 1005M 194M 761M 20% /usr/X11R6 /dev/wd0h 4.9G 248K 4.7G 0% /usr/local /dev/wd1b 2.0G 2.0K 1.9G 0% /usr/obj /dev/wd1e 12.4G 2.0K 11.8G 0% /usr/ports /dev/wd1a 2.0G 11.7M 1.9G 1% /usr/src /dev/wd1d 2.0G 8.1M 1.9G 0% /usr/xenocara /dev/wd0e 4.7G 4.6M 4.4G 0% /var ^^^^^^^^^^^^^^^^^^^^ Would it be interesting to get some other data from `show' commands in ddb?
