Fresh install of CentOS 4.4. uname -a, lspci, & lsusb output at bottom. I insert my 256MB USB key, light goes on, then off. Never mounts.

I've got an i386 server running centos 4.2 with 3 3ware controllers in it -- an 8006-2 for the system disks and 2 7500-8s. On the 7500s, I'm running an all software RAID50. This morning I came in to find the system hung. Turns out a disk went overnight on one of the 7500s, and rather than a graceful failover I got this: Jan 6 01:03:58 $SERVER kernel: 3w-xxxx: scsi2: Command

This includes two kernel patches, scsi-target and IO_CMD_EPOLL_WAIT. The former is a modified version of the scsi target infrastructure in mainline. The latter enables applications to handle AIO and non-AIO fds in the same loop. blktap uses the different patch, AIO event queue patch for the same aim. The IO_CMD_EPOLL_WAIT patch will be merged into mainline (and the AIO event queue will not) so

Hi! I tried to pcipassthrough usb-controllers to domu to use it with a memory-stick. First xen complained that the driver needs write-access to its configuration space, so I added these to pci-quirks. Since it still didn''t work I also added the device to pci-permissive but I still get an errormessage with Oops (at the end of this email) when sticking in the memory-stick. I tried

Most virtio setups have a fairly limited number of ring entries available. Enable S/G entry merging by default to fit into less of them. This restores the behavior at time of the virtio-blk blk-mq conversion, which was changed by commit "block: add queue flag for disabling SG merging" which made the behavior optional, but didn't update the existing drivers to keep their previous

Hi, These patches try to support multi virtual queues(multi-vq) in one virtio-blk device, and maps each virtual queue(vq) to blk-mq's hardware queue. With this approach, both scalability and performance on virtio-blk device can get improved. For verifying the improvement, I implements virtio-blk multi-vq over qemu's dataplane feature, and both handling host notification from each vq and

The first patch updates the data structure changes according to the spec proposal; the second patch actually implements the operations.
