Hi, all
I upgrade kernel version to 2.6.39 and find out a kernel panic when I test the MVSAS driver: kernel panic if hot-plug disk during I/O. But the driver is OK in version 2.6.37. And I test the AHCI driver in 2.6.39, the result is OK. I change queue-depth to 1 in 2.6.39, and kernel panic again. However, when add a printk debug statement in ata_sas_queuecmd function, and kernel panic is gone. According to the above, i think the bug is LIBSAS bug, may be is some lock issue. But can't find the real problem, so, please look at the issue. Thanks! See below for the log info:
