Title:
Broadcomm PCE-AC88 wifi drops out - system freezes
Status in linux-firmware package in Ubuntu:
Incomplete
Bug description:
With update 1.173.6 of linux-firmware (bionic-updates) a new firmware file
was installed :
/lib/firmware/brcm/brcmfmac4366c-pcie.bin
Package revision 1.173 does not have the 4366c file (it only has the 4366b
file).
Under 16.04 the ASUS PCE-AC88 was wrongly loading a 4366b firmware, and did
not work out of the box.
I followed instructions to retrieve the correct firmware from drivers
available on the manufacturer web site, and I was having no issue.
I upgraded my system to 18.04.2, and wifi worked very well until the
installation of linux-firmware 1.173.6, which came with bionic-
updates. After this update, the remotely operated server dropped the
wifi connection, requiring a local intervention, and had long freezes
making it drop connection and sometimes seem to fail to boot up.
In addition syslog was filled with messages:
brcmfmac: brcmf_msgbuf_alloc_pktid: dma_map_single failed !!
brcmfmac: brcmf_msgbuf_rxbuf_data_post: No PKTID available !!
I also had in kern.log:
[191882.330601] brcmfmac 0000:04:00.0: swiotlb buffer is full (sz: 2048 bytes)
[191882.330603] brcmfmac 0000:04:00.0: DMA: Out of SW-IOMMU space for 2048
bytes
[191882.330605] brcmfmac: brcmf_msgbuf_alloc_pktid: dma_map_single failed !!
[191882.330607] brcmfmac: brcmf_msgbuf_rxbuf_data_post: No PKTID available !!
Both pointing to potentially serious DMA problems.
When I noticed that my firmware had been overwritten, I recovered
another one from ASUS support web site, using the same method I had
used previously. The system and wifi now seem to work correctly.
This computer lacks an IOMMU. The problem might not occur on more
modern hardware equipped with a hardware IOMMU.
More information on the fairly old system (issue might be also
hardware dependent):
