It would be lovely if we could get to the bottom of this for once and for all.So to summarize my two mails: I think te use of dma_get_required_mask in mpt3sas is wrong, and the dma_get_required_mask return value from xen-swiotlb is also wrong. Fixing either one should fix this problem, and I think we should fix both.Hi all, Is there anything that can be done to get this fixed in xen and the kernel somehow?I keep having to manually patch the mpt3sas driver to prevent it from being able to switch to 32bit mode each time I upgrade the kernel.
Just use 5.10.173. Juergen
