The host is a Sharp SL-C3100 running Linux alarm 5.4.193, bridging from `pxa2xx-pcmcia`. I did some simple manual tracing, and the problem happens early: ``` ssb_host_pcmcia_probe (Initialization failed res=0,err=-EBUSY) `->...(res=0) `->ssb_bus_pcmciabus_register (err=-EBUSY) `->ssb_bus_register `->ssb_bus_scan `->ssb_pcmcia_switch_coreidx (matching errmsg) `->ssb_pcmcia_cfg_write (maybe) `->ssb_pcmcia_cfg_read (maybe) ``` Any suggestions?
