>Description:
While creating a new filesystem on a cgd disk (newfs cgd0a), kernel panics.
I'm using a 60 GB USB disk for my backups, and I wanted to encrypt my disk. First, I use cgdconfig, as described in man page. Then, restarted /etc/rc.d/cgd. While I want to create new filesystem, (filesystem creation started, inode numbers and some dots displayed and) an error occurred:
#newfs /dev/cgd0a
/dev/cgd0a: 57231.5MB (117210176 sectors) block size 16384, fragment size 2048
using 311 cylinder groups of 184.03MB, 11778 blks, 23296 inodes.
super-block backups (for fsck_ffs -b #) at:
32, 376928, 753824, 1130720, 1507616, 1884512, 2261488, 3015200,
...................panic: malloc: out of space in kmem_map
Stopped in pid 1241.1 (cron) at netbsd:cpu_Debugger+0x4: popl %ebp
db(1)>
I retried for a couple of times, and all of my attempts failed.
One of the fail reason is different from others:
uvm_fault(0xcc789540, 0, 1) -> 0xe
kernel: supervisor trap page fault, code=0
Stopped in pid 1053.1 (cron) at netbsd:pmap_create+0xf4: movl 0xbfc(%eax),%eax
db(0)>
>How-To-Repeat:
On NetBSD-4.0_STABLE (or maybe other versions also have this bug)
# cgdconfig -g -o /etc/cgd/sd0e -V disklabel aes-cbc 256
# cgdconfig -V re-enter cgd0 /dev/sd0e
# disklabel -W cgd0
# disklabel -e -I cgd0
# disklabel -N cgd0
(edit /etc/cgd/cgd.conf)
# /etc/rc.d/cgd restart
# newfs /dev/cgd0a
