A recent UML kernel with SLAB (linux-v3.9-rc2-188-g6c23cbb) holds just here in trinity output : [1050] [2174] getrlimit(resource=3, rlim=1) = -1 (Bad address) [1050] [2175] ustat(dev=4096, ubuf=4) = -1 (Invalid argument) [1050] [2176] mremap(addr=0, old_len=0x80000001, new_len=0xffa2, flags=1, new_addr=0) [watchdog] 2177 iterations. [F:1790 S:386] [watchdog] kernel became tainted! Last seed was 2735014321 after that the system hangs. I can still ssh into it from other console and run "ps -ef" , but even a "ps -ef | grep <bla bla>" then hangs too and can't be stopped via Ctrl.C. Furthermore "gdb -p <pid>" could not be run, b/c in the meanwhile the pids are vanished too (at least from /proc). And the syslog and anything else is empty. Host kernel is always 3.7.10. -- MfG/Sincerely Toralf Förster pgp finger print: 7B1A 07F4 EC82 0F90 D4C2 8936 872A E508 7DB6 9DA3 |
