Hello James, I write to you since you appear as the maintainer for the SCSI subsystem of the 2.6.x kernel. This is a report for a, possible, bug or hardware error. I would be grateful if you can help me figure out if it's a bug or a hardware error. Best regards, ------ Report Information: Problem: "Access to SCSI hard drive stoped working" Full Decription: "I have a server running Linux Debian 4 full patched that stopped responding to logins today. It also showed an errors like: *Warning*: session_start() [function.session-start <https://mabidp.interservices.com.ar/event_viewer/function.session-start>]: open(/var/lib/php5/sess_08d15059b3565084c88a2493cccd29bd, O_RDWR) failed: Read-only file system (30) in */usr/local/MABSEM/event_viewer/alerts_session.inc.php* on line *5* when trying to access to the webserver. There were no way to access to the system, event the consoles did not responded after typing the username, so I needed to power off the system. Afterwards in the logs I found an error related to SCSI (the error continue to appear but the system is working fine). Could you please tell me what could be the cause of this error and if it is the cause of the system failure?"
