https://bugzilla.kernel.org/show_bug.cgi?id=60644 --- Comment #37 from Jeff Johnson <jeff.johnson@xxxxxxxxxxxxxxxxx> --- I can confirm Tommy's observations about disabling PERR and SERR solving the issue. The motherboard I am using (Supermicro X8DTH-iF) does not have those exact BIOS settings to control. In my case the following BIOS changes and kernel command line arguments eliminated the issue: MB BIOS: BIOS->Advanced->Advanced Chipset Configuration->North Bridge Configuration->ASPM=Disabled Linux boot command line options: pcie_aspm=off disable_msi=1 With these changes a very intense fio run has gone four days without a single error or issue on a Linux-ZFS filesystem. Before these changes I could not go four hours without multiple HBAs disappearing (in my config there are three HBAs). Sometimes the HBAs would disappear within 15-20 minutes of benchmark runtime. -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
