My apologies,

The stable tag v5.4.289 seems to fail to boot with the following prompt in an infinite loop:
[   24.427217] megaraid_sas 0000:65:00.0: megasas_build_io_fusion 3273 sge_count (-12) is out of range. Range is:  0-256

Reverting the following patch seems to fix the issue:

stable-5.4      : v5.4.285             - 5df29a445f3a xen/swiotlb: add
alignment check for dma buffers

I tried changing swiotlb grub command line arguments but that didn't
seem to help much unfortunately and the error was seen again.

Thanks & Regards,
