latest 2.2.25 Hibernation patch raises 100% cpu usage
Hi,
I use the xi Debian packages, the current 2.2.25 auto 47 build seams to include the commit 351aa01c6e I think this commit cases a 100% cpu usage.
After some time 1-5 minutes the hibernate process uses 100% and strace floods the screen with:
epoll_wait(9, {{EPOLLIN|EPOLLHUP, {u32=2609346112, u64=140044312999488}}, {EPOLLIN|EPOLLHUP, {u32=2609364288, u64=140044313017664}}, {EPOLLIN|EPOLLHUP, {u32=2609380304, u64=140044313033680}}}, 34, 164437) = 3 epoll_wait(9, {{EPOLLIN|EPOLLHUP, {u32=2609346112, u64=140044312999488}}, {EPOLLIN|EPOLLHUP, {u32=2609364288, u64=140044313017664}}, {EPOLLIN|EPOLLHUP, {u32=2609380304, u64=140044313033680}}}, 34, 164437) = 3 epoll_wait(9, {{EPOLLIN|EPOLLHUP, {u32=2609346112, u64=140044312999488}}, {EPOLLIN|EPOLLHUP, {u32=2609364288, u64=140044313017664}}, {EPOLLIN|EPOLLHUP, {u32=2609380304, u64=140044313033680}}}, 34, 164436) = 3 epoll_wait(9, {{EPOLLIN|EPOLLHUP, {u32=2609346112, u64=140044312999488}}, {EPOLLIN|EPOLLHUP, {u32=2609364288, u64=140044313017664}}, {EPOLLIN|EPOLLHUP, {u32=2609380304, u64=140044313033680}}}, 34, 164436) = 3 epoll_wait(9, {{EPOLLIN|EPOLLHUP, {u32=2609346112, u64=140044312999488}}, {EPOLLIN|EPOLLHUP, {u32=2609364288, u64=140044313017664}}, {EPOLLIN|EPOLLHUP, {u32=2609380304, u64=140044313033680}}}, 34, 164436) = 3 epoll_wait(9, {{EPOLLIN|EPOLLHUP, {u32=2609346112, u64=140044312999488}}, {EPOLLIN|EPOLLHUP, {u32=2609364288, u64=140044313017664}}, {EPOLLIN|EPOLLHUP, {u32=2609380304, u64=140044313033680}}}, 34, 164436) = 3 epoll_wait(9, {{EPOLLIN|EPOLLHUP, {u32=2609346112, u64=140044312999488}}, {EPOLLIN|EPOLLHUP, {u32=2609364288, u64=140044313017664}}, {EPOLLIN|EPOLLHUP, {u32=2609380304, u64=140044313033680}}}, 34, 164436) = 3 epoll_wait(9, {{EPOLLIN|EPOLLHUP, {u32=2609346112, u64=140044312999488}}, {EPOLLIN|EPOLLHUP, {u32=2609364288, u64=140044313017664}}, {EPOLLIN|EPOLLHUP, {u32=2609380304, u64=140044313033680}}}, 34, 164436) = 3 epoll_wait(9, {{EPOLLIN|EPOLLHUP, {u32=2609346112, u64=140044312999488}}, {EPOLLIN|EPOLLHUP, {u32=2609364288, u64=140044313017664}}, {EPOLLIN|EPOLLHUP, {u32=2609380304, u64=140044313033680}}}, 34, 164435) = 3
Maybe its a client thats incompatible, downgrading to version +46 solve the problem.
