(I'm cross-posting to linux-scsi in case anyone has seen this)
I've got this controller and drive for a couple more days for testing, and I'm
planning on ordering one. Any ideas on how I might track the problem down? I
haven't poked around the kernel scsi code much.
I thought this had already been tracked down to this alpha version of GCC having
broken use of the PACKED attribute on data structures?
Fix the compiler if you want the driver to compile correctly, or use an earlier
compiler like 2.6.3 that works properly.
