I have now installed 2.6.34.7-0.7-default kernel Actual Results: The smbd process is eating 100% of the first core and then system spits every 60s the same bug. smbd process is unkillable and OS is impossible to shutdown correctly. ----------- PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 2833 mach 20 0 37508 4512 3324 R 100 0.1 42:45.46 smbd Intel(R) Pentium(R) D CPU 3.00GHz stepping 05 4GB RAM 2cores -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
