Re: wireless on debian on Ultra10

booting the kernel 4.18.0-1-sparc64
I dont view error "can't ioremap BAR 0"

and all 3 wireless cards "ifup"  regularly


if I run: 
dmesg|grep rt2500pci

I view:
[   57.116343] rt2500pci 0000:02:03.0: enabling device (0000 -> 0002)
[   58.378196] rt2500pci 0000:02:03.0 wlp2s3: renamed from wlan0
[  621.480733] rt2500pci 0000:02:03.0 wlp2s3: disabling HT as WMM/QoS is not 
supported by the AP
[  621.480762] rt2500pci 0000:02:03.0 wlp2s3: disabling VHT as WMM/QoS is not 
supported by the AP


p.s.
I have system crash if I run kernel 4.9.0
