Sharvari and other NXP developers: Do you have some internal testing of this pcieusb8997_combo_v4.bin firmware for PCIe+USB variant of 8997 wifi chips? Or are you aware of this issue and do you have in NXP some workaround for it (e.g. at driver level)? Could you please look at this serious issue and try to debug firmware and release a new version, as this is obvious fatal error in firmware itself? Josh, how you in linux-firmware repository handle such, I must say, "fatal issues"? Wait for vendor fixes or revert problematic commits? Or something else? Because when users starts upgrading linux-firmware packages in their downstream distributions then basically wifi cards on this 8997 chips with official mwifiex driver stops working. > > REF (and all details of tests) : > > https://github.com/NXP/mwifiex-firmware/issues/1 > > > > > > Broken firmware : > > > > Version |W16.68.1.p195| of |pcieusb8997_combo_v4.bin| was included into > > linux-firmware repository by this pull request: > > https://lore.kernel.org/all/CA+5PVA5yQbjg3vaT7F8120B6ngLn7+sZC0OWt0KoUiQR9hS4FA@mail.gmail.com/ > > > > > > And latest version |W16.68.10.p159| of |pcieusb8997_combo_v4.bin| by > > this pull request: > > https://lore.kernel.org/linux-firmware/CA+5PVA5on7+CRtEV7tThPxgucwt3W9i-tEXm4cgH-AmMB-Jrtg@mail.gmail.com/ > > > > > > Olders looks to works better. > > > > In quick tests, they allow more than 1 clients at a time ! > > > > I am still testing the V16.68.1.p145 and report the results after some > > longer use... > > > > Hopes it will help... > > Regards, > > Gérald Kerma > > gandalf(at)gk2(dot)net >
