Package: firmware-iwlwifi
Version: 20251111-1
Severity: minor

Dear Maintainer,

While streaming some of the talks from this year's FOSDEM conference
on my ThinkPad X1 Yoga laptop, an error seems to have occurred in the
microcode of the Intel Wireless 8260 chipset.

The top-level error message (Microcode SW error detected) is the same
as currently-open bugreports #700629 and #1026906, but the identifier
displayed at the top of the microcode stacktrace (NMI_INTERRUPT_WDG)
doesn't appear in those, but does appear in previously-reported,
closed bug #934781.

Please find the error report and some surrounding context from the
output of journalctl attached with this bugreport.

Regards,
James
