Package: dosemu
Version: 1.4.0+svn.1999-1
Severity: normal
With the latest kernel upgrade in Lenny, dosemu no longer runs. This
report's main purpose is to suggest updating dosemu on Lenny so that it
at least tells people what is going on and how to fix it. I also report
an odd mix of successes and failures running the latest version of
dosemu without altering vm.mmap_min_addr.
# after 2.6.26 kernel update and reboot
# dosemu ran fine before this
$ dosemu &
[1] 11627
$ ERROR: $_dosmem = (768) not allowed for X and VGA console graphics,
restricting to 640K
LOWRAM mmap: Invalid argument
[1]+ Segmentation fault dosemu
I was also surprised the backporting from unstable did not run. Here
are the results afer building it locally and installing it:
$ dosemu &
[1] 21452
$ ERROR: $_dosmem = (768) not allowed for X and VGA console graphics,
restricting to 640K
LOWRAM mmap: Operation not permitted
Cannot map low DOS memory (the first 640k).
You can most likely avoid this problem by running
sysctl -w vm.mmap_min_addr=0
as root, or by changing the vm.mmap_min_addr setting in
/etc/sysctl.conf or a file in /etc/sysctl.d/ to 0.
[1]+ Exit 99 dosemu
I was surprised because that worked fine on another system (with a
2.6.32 kernel). That system is amd64 architecture, intel chips, and
hardware virtualization.
This system (with the stock 2.6.26 kernel) is 32 bit with AMD chips and
no virtualization. I see earlier in this bug that emulation must be
enabled to allow access to memory location 0, so it is perhaps not
surprising that it doesn't work--but is surprising that it works on the
2.6.32 system.
While it's true that people who run into this problem on Lenny can find
a solution on the internet, that's not a particularly friendly way to
handle the problem--particularly since dosemu was working before the
upgrade.
Note the version number on the bug reflects the backported unstable
version on my system. The bug applies to the stable version.
