Good Evening,
I have come accross a reproducable panic in bother 5.2-Release and 5.2-Current
(as it was an hour ago). To perform this, I create two 750Mb memory disks,
format them and mount them. The machine has 2Gb of RAM, of which no more then
90mb is active.
Then when I attempt to copy data to the first of the memory disk it causes a
panic after it's copied an amount of data onto the memory disk. I could be
missing some major kernel/sysctl configuration option here, but I'm not sure.
[xenon:~]# mdconfig -a -t malloc -s 750m
md0
[xenon:~]# mdconfig -a -t malloc -s 750m
md1
[xenon:~]# newfs -U /dev/md0
/dev/md0: 750.0MB (1536000 sectors) block size 16384, fragment size 2048
using 5 cylinder groups of 183.77MB, 11761 blks, 23552 inodes.

[xenon:~]# newfs -U /dev/md1
/dev/md1: 750.0MB (1536000 sectors) block size 16384, fragment size 2048
using 5 cylinder groups of 183.77MB, 11761 blks, 23552 inodes.

[xenon:~]# cd /usr
[xenon:/usr]# mount /dev/md0 src
[xenon:/usr]# mount /dev/md1 obj
[xenon:/usr]# cd src
[xenon:/usr/src]# cp -Rp ../src-orig/* .
The backtrace follows, I have saved the dump file, however it is 2Gb so that
negates me sending it to anyone. If you want to have a poke with gdb your
welcome to, contact me and I'll arrange for SSH/root access on the machine.
