Hi,

The dump device is set to use the swap partition on my machine, but it
doesn't do the trick, since no dump is saved at all. I tried some
different approaches from single user mode, but with no success.

All I can give you is the short DDB trace output that reads:

strlen(6,d2434a88,c03ea780,c01d5d19,c0312144) at strlen+0x8
iconv_sysctl_drvlist(c03ea5e0,0,0,d5450bf8,d5450bf8) at
iconv_sysctl_drvlist+0x63
sysctl_root(d5450bf8,d5450c2c,4,d5450bf8,0) at sysctl_root+0x10b
userland_sysctl(d5450c80,3,0,bfbfeca0,0) at userland_sysctl+0x104
sys___sysctl(d5450cf0,d5450d00,18,0,6) at sys___sysctl+0x03
syscall2(d5450d40) at syscall2+0x20c
Xint0x80_syscall() at Xint0x80_syscall+0x35

..that's all I can get out of it -- I hope I got everything right
since I had to transfer the output manually into this message. I
attached the "screenshot" I've taken with my mobile's camera, but it's
even worse than page fault itself.

Enjoy the show
