Hi all. I am new to the list. I am trying to make a SD flash bootable. I have a MSI Wind netbook running Fedora 9 with a built-in card reader that detects the SD flash properly. However, when I run syslinux, it does not update the boot block. I also tried using a SD -> USB adapter, but I get the same behavior. Fedora 9 uses an older syslinux 3.61, but I also tried the latest 3.72 with

Hi, I work on a support team for the Sun StorEdge 6920 and have a question about the use of the SCSI sync cache command in Solaris and ZFS. We have a bug in our 6920 software that exposes us to a memory leak when we receive the SCSI sync cache command: 6456312 - SCSI Synchronize Cache Command is flawed It will take some time for this bug fix to role out to the field so we need to understand
