Hello, Dmitry, Mochel and James.
I've been looking at sd code and found seemingly bogus 'if (!sdkp)'
tests with /* this can happen */ comment. I've digged changelog and
found out that this was to prevent oops which occurs if some driver
gets stuck inside -probe and the machine goes down and

Hi,
scsi_allocate_request() doesn't hold a reference to the device that it
points to, that is not good. This patch fixes that up.

Hi,
There is a problem with the way sdev is freed currently. The reason is
really that there is a circular referencing problem: the sdev needs to
hold on to the queue, but the queue (through the request function) also
needs to hold on to the sdev.

Sergey, I'm assuming this is a bug in the megaraid driver.
Can you confirm that it's still happening in 2.6.12-rc1?

Hi,
There has been a running thread for a while on several mailing lists
concerning PCI bus error recovery. Very breifly, some architectures
have PCI error recovery mechanisms built into them (e.g. IBM PowerPC,
also new PCI-Express chips from Intel (and other vendors) and possibly
pa-risc and

This patch updates the driver for the 3ware 5/6/7/8000 series to do
the following:
- Increase max ioctl buffer size to 512 sectors.
- Make tw_scsi_queue() return 0 for 'Unknown scsi opcode'.
- Fix tw_remove() to free irq handler/unregister_chrdev() before shutting down
