Hi, we at the Debian project just upgraded one of our machines from kernel version 2.6.32.60 to 3.2.41. Now the system hangs hard after about an hour of uptime without any trace whatsoever on the Operating System Messages (it's running in LPAR mode with 2 IFLs assigned).
Does this ring a bell to anyone? Is there some known deadlock problem that has been fixed in a later kernel ? If not, does somebody know how to debug that? I could try the dump process, but I'm not sure what I could do with the result[1]. And it does not seem to panic or crash or log anything into HW messages. It is possible to issue a SysRq through OS Messages anyhow? Kind regards Philipp Kern [1] I cannot ask a vendor or open a PMR, in any case. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
