We got the following report in Debian after an update from 5.10.140 to

regressions?

Only three mpt3sas changes are new in v5.10.149 compared to v5.10.140:
$ git log --format=oneline v5.10.140..v5.10.149
2b9aba0c5d58e141e32bb1bb4c7cd91d19f075b8 scsi: mpt3sas: Fix return value check of dma_get_required_mask()
e7fafef9830c4a01e60f76e3860a9bef0262378d scsi: mpt3sas: Force PCIe scatterlist allocations to be within same 4 GB region
ea10a652ad2ae2cf3eced6f632a5c98f26727057 scsi: mpt3sas: Fix use-after-free warning

Sreekanth and Suganath, can you help with bisecting this issue? For the
full report, see also https://lore.kernel.org/linux-scsi/Y1JkuKTjVYrOWbvm@xxxxxxxxxxx/.

Thanks,
