[uml-devel] Error messages booting 2.6.16-pre3

[uml-devel] [Bug 111575] sys-kernel/usermode-sources-2.6.14: kernel panic when assigning more than 256M
Clear-Text: http://bugs.gentoo.org/show_bug.cgi?id=111575 Secure: https://bugs.gentoo.org/show_bug.cgi?id=111575 --- Comment #20 from [EMAIL PROTECTED] 2006-02-15 15:15 PST --- The report says switching "CONFIG_MODE_TT" off helped. And currently, there is no known reason for which a user should need to enable TT mode. So, this bug can be IMHO considered RESOLVED (since it's a configuration not recommended, it would turn out to be RESOLVED INVALID, likely). -- Configure bugmail: http://bugs.gentoo.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are on the CC list for the bug, or are watching someone who is. --- This SF.net email is sponsored by: Splunk Inc.

[uml-devel] Fixed the uml_moo 64-bit COW bug
Ok, here we are. uml_moo was not portable to 64-bit AMD for some portability
bugs.
1) I fixed bug one, SIGFPE at startup of uml_moo or at boot of UML kernel
("Kernel mode signal 8"), time ago. The resulting binary completed the merge,
but the results were wrong, compared with the results from a 32-bit binary.
The SIGFPE bug at boot meant another issue too - 64-bit binaries of uml_mkcow
and of kernel binaries use a different format than 32-bit ones.
2) Today I discovered the 2nd bug, tested the result, and got everything
working - it produced the correct results even on a 500Mb UBD with a 270 Mb
COW file (I had done a dist-upgrade with months of security updates).
This second bug, luckily, doesn't affect the kernel - otherwise 64-bit kernel
would have corrupted data in COW files.
After refining the code and preparing for release, I'll publish the complete
fixes, and a new uml-utilities release. I expect to do this in this week.
