Hi List, Any ideas what is wrong with controller? It is running latest 5.x series of centos and driver spills out following warnings at random times: mptbase: ioc0: WARNING - IOC is in FAULT state (1600h)!!! mptbase: ioc0: WARNING - Issuing HardReset from mpt_fault_reset_work!! mptbase: ioc0: Initiating recovery mptbase: ioc0: WARNING - IOC is in FAULT state!!! mptbase: ioc0: WARNING -

Verifying a report I just got pinged about, building vanilla openssh 7.7p1 on linux configures ok, but fails build around 'retpoline' I've started looking through recent reports; haven't _yet_ found anything similar. While I continue, is any of the following familiar/expected? Either known bug/issue or env conflict? The current env includes supposedly retpoline-ready GCC 8.1.1,

Hello all, I?m at my wits end trying to resolve this. We are running centos 4.5 on Intel hardware. Dual SCSI disk drives mirrored on an LSI Logic controller. Every once in a while and not always on the same server and not only on the local SCSI Drives. System A ? Dual internal drives on /dev/sda System B ? Dual internal drives on /dev/sdc with a DAS on /dev/sda. Each of these

Add virtio pstore device to allow kernel log files saved on the host. It will save the log files on the directory given by pstore device option. $ qemu-system-x86_64 -device virtio-pstore,directory=dir-xx ...

I just tried asan on an optimized 32 bit build of ------------------------------------- #include <stdint.h> __attribute__((noinline)) void f(uint64_t *p) { *p = 42; } int main() { void *p; f((uint64_t*)&p); } ------------------------------------ and it correctly catches the invalid access. If I comment the attribute, the optimizers find and exploit the undefined behavior and

I find IoC to be a helpful concept in general and, having glanced at a few existing Rails app.s, I
