hi claudio,

> Could you share a dmesg and the stack traces of these panics?

ive attached the dmesg as a text file, the stack traces are:

> On first look it looks like your diff changes too many things at once

my apologies! just to clarify my changes in case it helps:
- i expanded the fwdl ring size to 64 because the firmware image is large and a
16 slot ring fills up pretty quickly and starts stalling

(both in mwx_dma_tx_cleanup)
- the boot thread and interrupt handler were calling cleanup at the same time,
so splnet stops the race between them
- if an interrupt fired while m_freem was running the interrupt handler would
see the non null pointer and call free a second time

- in mcu_alloc_msg, m_adj was shifting m_data forward by 32b, so when send_msg
copied firmware stuff into it, it wrote past the buff boundary into kernel mem
- in mcu_send_buf when m_data was updated it was updating m_len along with it
but, it was not updating m_pkthdr.len
- in load_firmware the chunk size + desc header was more than 4096b as far as i
could tell, so subtracting just makes it fit cleaner
- in mcu_send_firmware it was queueing the data faster than the pcie dma engine
could transmit it

> I wonder why I'm not seeing those panics.

my best guess is that because i tested it on an openbsd guest with my physical
mt7921 card passed through via pcie/vfio, it might(?) have added some latency,
because these issues only occured sometimes

regards,
unium
