--- Comment #34 from Alan Somers <asomers@FreeBSD.org> ---
I can reproduce this on a build based on 13.1-RELEASE, but only if I load the
kernel module late.  If I load if from /boot/loader.conf, or from kld_list in
/etc/rc.conf, then it works fine.  But if I load it by hand with "kldload
if_bnxt" after booting has completed, then I get the same
"iflib_dma_alloc_align: bus_dma_tag_create failed: 22" error that others
report, and no bnxt devices are created.  However, if I then unload the module
and load it again, it works on the second try.

I cannot reproduce the problem on 14.0-CURRENT simply because on that version,
something causes the module to load automatically.  And I can't unload the
module to try again due to bug #270270.

My firmware is:
dev.bnxt.0.ver.roce_fw: 214.0.194
dev.bnxt.0.ver.netctrl_fw: 214.4.7
dev.bnxt.0.ver.mgmt_fw: 214.4.42
dev.bnxt.0.ver.hwrm_fw: 214.4.91
