It and the PMP support seem to like that location much better - I'm successfully creating an array at the moment. The system still responds, but accessing currently running filesystems (another array and the local scsi boot disk) seems to "freeze" for 20-30 seconds. I was able to move the graphics card to another slot (which for a period in the past was also limited to the first PCI slot). Maybe this will make sense to some folks out there - thanks! ...tom Jeff Garzik wrote: > Tom Evans wrote: >> Have you heard of such and issue with the 3124-2/4276 combination? >> Is anyone else trying this driver on an Alpha? > > Alpha should not be operationally much different from other little > endian 64-bit platforms. > > The PCI swizzle might be weird (what is your Alpha platform?), is the > only Alpha-specific thing that comes to mind. > > >> I have similar such behavior before when using drivers that generate >> many unaligned accesses - I only have seen 2 places they occur in >> sata_sil24 and have fixed them myself, but that made no difference. > > We definitely want to fix all these you find.
