https://bugzilla.kernel.org/show_bug.cgi?id=199435 --- Comment #14 from Anthony Hausman (anthonyhaussmann@xxxxxxxxx) --- Indeed I have a charged battery (capacitor) and the writeback-cache enabled. I run the hp-health component too, I have already try to disable it on the 4.11 kernel and have reproduced the problem of load without it. The cma related call trace up after the logical drive reset is called. Right now, I test on a server the kernel 4.16.3-041603-generic with the hpsa module with the patch to use local work-queue insead of system work-queue. Right now I didn't reproduce the problem. I had a disk with bad blocks (before launching a read-only test badblocks returned a lot of block error) but since I have upgraded the kernel with the patch hpsa module I have no more error. I'm still trying to reproduce the problem by launching a badblocks read-only test on the "ex-faulty" disk. I'll tell you the result of the test. -- You are receiving this mail because: You are the assignee for the bug.
