- uptime : 25 days, 23:26
no issues afaics

dmesg has "random":  - but previous fw had those too afaik
[1521427.440784] ath: phy0: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x02100020 DMADBG_7=0x00006400

and 21.02-rc1 on
ath79 NAND GLinet AR750S NOR-NAND in Client Mode to above WDR-3600 = works
ath79 Sitecom WLR-8100 in Client Mode to above WDR-3600 = works

+ USB Sticks of

- mt76x0u (1 stream: TP-Link T2U)
- mt76x2u (2 stream: AVM Fritz AC860)
- ath9k_htc (2Stream Netgear WNDA3200)
- rt73usb
= attached to GLINET AR750S / Sitecom WLR-8100 and client mode -> worked*

* USB3 on Sitecom not working /usable is probably upstream bug 

21.02-rc2 on x86-64 (Atom 330 : Intel D945GCLF2) (PXEBoot initramfs kernel)
client with
- mt76x0u (1 stream: TP-Link T2U)
- mt76x2u (2 stream: AVM Fritz AC860)
- ath9k_htc (2Stream Netgear WNDA3200)
on USB2 
= works

invalid/minor issue:
btrfs kernel module on dmesg reports

[    2.275335] btrfs: Unknown symbol zlib_inflateInit2 (err -2)
[    2.275644] btrfs: Unknown symbol zlib_inflate (err -2)
[    2.275851] btrfs: Unknown symbol zlib_inflate_workspacesize (err -2)
[    2.276362] btrfs: Unknown symbol zlib_inflateEnd (err -2)

this happens probably because of using openwrt-initramfs-kernel for PXEboot / invalid usage

replicated with qemu via
qemu-system-x86_64 -M q35 -kernel openwrt-x86-64-generic-initramfs-kernel.bin -hda openwrt-x86-64-generic-ext4-combined.img -append "root=/dev/sda2"
