1369990198 M * hamann1 hey there
1369990205 M * hamann1 last night we had a complete crash of one of our production boxes
1369990219 M * hamann1 we're not sure what's the reason, so could someone please take a look at https://gist.github.com/hamann/adab08b3b15b88bc908d
1369990240 M * hamann1 we've upraded the kernel from 2.6.32 to 3.2.44 two weeks ago, and it's the first time something like that happend in 4 years
1369990261 M * hamann1 is it a kernel bug? should we upgrade to 3.6.11?
1369990980 M * Ghislain what make you think it could be vserver related ?
1369990992 M * Bertl the first trace is definitely a kernel bug or a hardware problem
1369991036 M * Bertl the rest seems like follow ups, watchdog hitting, cpu stuck, etc
1369991124 M * hamann1 i don't know if it's vserver related :/
1369991153 M * Bertl now, the fact that shortly before the kernel bug occured, your logs show ACPI errors, suggest that an ACPI function is called which might have unexpected sideeffects
1369991153 M * Ghislain i had a lot of issues with 3.2 all gone since i use 3.4 but beng kernels are pretty safe even in 3.2
1369991517 M * hamann1 ok, thanks. so, what's your recommendation?
1369991650 M * Bertl my recommendation would be to either fix the ACPI or disable whatever is calling into it (sensors maybe?)
1369993249 M * hamann1 so I'll disable the ipmi calls, don't have a clue how to fix acpi :)
1369993705 M * Bertl will most likely fix the issue, but upgrading to a newer kernel won't hurt
1369994164 M * Bertl off for now ... bbl
1369994172 N * Bertl Bertl_oO
1369994183 M * hamann1 ok, thank you!

1370003850 M * alpha_one_x86 Hello, no patch for the 3.8? why?
1370003866 M * alpha_one_x86 The 3.7 don't apply
1370004925 M * arekm no one paid for 3.8 development but there is a chance for 3.9 patch very soon from what Bertl says
1370004942 M * alpha_one_x86 blkio.io_wait_time -> no into cgroup with vserver?
1370005075 N * Bertl_oO Bertl
1370005143 M * Bertl well, it was more that I had no spare time and nobody considered it important enough to pay for my time ... as arekm said, this is about to change
1370005171 M * Bertl alpha_one_x86: what do you mean with the last 'question'?
1370005287 M * alpha_one_x86 Bertl: I try get the IO by vm via cgroup, kernel have the correct config, but I don't see any blkio.io_wait_time
1370005598 M * Bertl but it is there on a cgroup not created for a guest?
1370005667 M * alpha_one_x86 I have some value (like tasks, ...)
1370005848 M * Bertl sounds like your kernel (which one is it?) does not support blkio.io_wait_time then, or doesn't have it enabled
1370005875 M * alpha_one_x86 I have the 3.7 + all is enabled into the kernel
1370005887 M * alpha_one_x86 It's why I don't understand
1370006002 M * Bertl CONFIG_BLK_CGROUP=y and CONFIG_CFQ_GROUP_IOSCHED=y ?
1370006095 M * alpha_one_x86 yes for both
1370006419 M * Bertl could you upload the cgroup entries you have for this guest? (i.e. a list to a pastebin or so)
