This page provides a list of the known bugs in XOS
version 4.5.0. In general this only includes outright bugs. It does
not include features that are simply not implmented or not complete.
With the major changes between version 3 and 4, there are quite a
few such incomplete features due to modules that simply have not
been fully updated from version 3.
As it stands, this list is woefully incomplete.
It will be updated as bugs are reported and as they are fixed.
Please report any other bugs observed or any additional information
about reproducing any of the bugs listed here to
If the file specified to the bootstrap is not found
the bootstrap must be restarted (with ctl-alt-DEL) before it will
be able to load a different file.
USB related problems:
Failures (IO errors and system crashes) have
occasionally been observed associated with the OHCI USB controller.
Any information on reproducing this would be appreciated.
The system may crash if a USB disk is accessed while
it is being mounted.
Keyboard and command shell related problems:
Type-ahead of non-ASCII keys of more than one key
press is lost.
Editing (inserting and/or deleting) characters before
the end of a line occasionally inserts extra spaces at the end of the
line. Any information on reproducing this would be appreciated.
The command shell (XSHELL) can get into a state where
all input appears to be ignored. Entering a local command (such as
CLS) usually restores normal operation. Any information on
reproducing this would be appreciated.
XWS (GUI) problems:
Keyboard input to edit windows has numerous problems.
This is currently being worked on.
Scroll bars on windows do not work. This is also
being worked on.
