Dosemu 1.2.0 & kernel 2.6 crash

Dosemu 1.2.0 & kernel 2.6 crash

[Disnel]

Thanks for new dosemu. It works for me with 2.4 kernel. But I'am unable
to run it with 2.6 kernel, it crashes every time when I try to start it.
Setting mapping to mapfile in dosemu.conf does not help.

Here is what it writes to console:

means your DOS code went into zombie land. Strange.

well I don't know what 2.6.0-1.104custom is. There may be all sorts of
patches applied.

Can you
* check with the plain Linus 2.6.1 kernel -- if it works with 2.6.1 you
  should report a bug to the 1.104 custom patchers.
* check dmesg output (kernel log messages)
* if all else fails, try to link statically (linkstatic on in
  compiletime-settings)

Checked with 2.6.1 from unofficial rpms compiled by
bhcompile@porky.devel.redhat.com, results are the same. Plain Linus
2.6.1 kernel still does not work for me in RH9 (some problem with
initrd, needed modules failed to load, I don't know why, yet, I'll try
to solve it). 2.6.0-1.104custom is kernel from similar rpms compiled by
myself (i turned off APM support).

Ok, I'll try that someday (probably next week).

you could try to turn off the 4G/4G trampoline or any other highmem

DOSEMU may well have problems with 4G/4G today -- most likely someone will
solve them in the future though.
