CentOS IRQ Errors, Server: kernel: Disabling IRQ #177
Recently we have been doing a lot of testing of oclHashcat on CentOS Linux servers. The oclHashcat application takes advantage of the GPU’s, or Graphical Processing Units, of Nvidia graphics cards or ATI graphics cards. Anyhow one of the servers we have been testing with has four Nvidia 295 GTX’s and at times was receiving an error stating the kernel was disabling the IRQ. Below we describe the error in more detail along with a kernel parameter that was added to resolve the error. Even though we experienced this issue with oclHashcat specifically the error could happen with other applications and/or Linux Operating Systems so the resolution could be the same.
