I have been running several UML instances on older kernels for some time hoping to see a fix for the random issue. However, a recent upgrade to 2.6.26-rc5 now reults in periodic boot failures of the virtual systems. Downgrading to 2.6.25-rc2-mm1 returns to previous behavior (reliable boot, but other issues).
This is running on a host with SKAS3 patches applied (2.6.21.6-skas3-v8.2) in a chroot'ed environment (/proc/mm is mounted in the chroot). Unfortunately, I'm uncertain of what information will help. Here is the output from a strace on an instance that "froze" during boot: # strace -p 4997 Process 4997 attached - interrupt to quit restart_syscall(<... resuming interrupted call ...> I never moves beyond this point. The console output for this "freeze" is here: Locating the top of the address space ... 0xc0000000 Core dump limits : soft - 0 hard - NONE Checking that ptrace can change system call numbers...OK Checking syscall emulation patch for ptrace...OK Checking advanced syscall emulation patch for ptrace...OK Checking for tmpfs mount on /dev/shm...failed to open /proc/mounts, errno = 2 Checking PROT_EXEC mmap in /dev/shm/...OK Checking for the skas3 patch in the host: - /proc/mm...found - PTRACE_FAULTINFO...found - PTRACE_LDT...found UML running in SKAS3 mode This is a show-stopper for upgrading as: 1. What instances fail to boot change every time the host is rebooted. 2. Once an instance decides to fail, to further attempts to start it will succeed until I downgrade the kernel. Ideas?
