Just don't do that, I'm surprised it's just one warning - UML drivers were often SMP unsafe and debugging options caused various warnings, the -rt patch will break it even more. My knowledge is from the last time I was developing on that, but not much activity has happened since. _Anyway_, you could maybe disable consoles and use just ssh or maybe uml_mconsole (there was some way to get console output) - the "winch" IRQ, which is mentioned, is IIRC about handling console-handling signals, SIGWINCH for terminal resize. > Starting Client Machine with eth0 ip as 192.168.10.2 > Locating the bottom of the address space ... 0x0 > Locating the top of the address space ... 0xffffd000 > 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...OK > Checking PROT_EXEC mmap in /dev/shm/...OK > Checking for the skas3 patch in the host: > - /proc/mm...not found: No such file or directory > - PTRACE_FAULTINFO...not found > - PTRACE_LDT...not found > UML running in SKAS0 mode > Adding 12148736 bytes to physical memory to account for exec-shield gap > Linux version 2.6.33.7-rt29 (r...@dasaradham-laptop) (gcc version > 4.4.3 (Ubuntu 4.4.3-4ubuntu5) ) #8 Tue Aug 31 21:39:42 IST 2010 > Built 1 zonelists in Zone order, mobility grouping on.
