FS#2969 - ramips/mt7621: hang up while booting if pcie0 is not connected #7805
Comments

cliobrando: I can replicate the same behavior using the latest master and a ZBT we1326. |
|
musashino205: This issue was fixed by he commit 51c6b14.

musashino205:
I tried the self compiled firmware with latest source on I-O DATA WN-AX1167GR2. But the kernel hangs up while booting after the pcie related messages.
This problem didn't occur on other models using pcie0 (WSR-2533DHPL, etc). I haven't checked it yet, it may happen in WN-DX1167R as well.
