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,
Harshvardhan
