hello all, I'm having serious issues running UML guest on amd64:
On the 64bit (gentoo) host with vanilla 2.6.14.2 + skas3-v9-pre7 and
guest vanilla 2.6.14.2 + uml-2.6.14-bs3.patch when I try to run
/uml/bin/linux ubd0=root_fs ubd1=swap_fs
I got
Kernel panic - not syncing: map_stub_pages : /proc/mm map for code
failed,err = 22
this happens for both a 64 and 32bit guest root_fs.
I've also tried in chrooted 32bit and recompile/repatch the guest
kernel with or without SUBARCH=i386 but the result is that it freeze just a
line before: VFS: Mounted root (reiserfs filesystem) readonly. with 90%
cpu used
appending mode=skas0 here is the full output. it looks there are other
errors... what do you advice to
1- get skas3 working
2- fix skas0 other error
Don't know what to try next ...
thanks in advance
Checking PROT_EXEC mmap in /tmp...OK
Checking for the skas3 patch in the host:
- /proc/mm...found but disabled on command line
- PTRACE_FAULTINFO...found but disabled on command line
- PTRACE_LDT...found
UML running in SKAS0 mode
Checking that ptrace can change system call numbers...OK
Checking syscall emulation patch for ptrace...missing
