I was checking out on a linux filesystem which strangely couldn't create some
utf8 filenames.
I checked out via the wired interface in Haiku, then all was fine.
I have some questions though, as I didn't manage to bring up the interface yet.
These are the ralinkwifi driver's entries in the syslog:
KERN: [ralinkwifi] (ral) bus_alloc_resource(3, [16], 0x0, 0xffffffff, 0x1,0x2)
KERN: [ralinkwifi] (ral) bus_alloc_resource(1, [0], 0x0, 0xffffffff, 0x1,0x6)
KERN: [ralinkwifi] (ral) could not allocate interrupt resource
I found the error message in if_ral_pci.c, at line 202
This is the code part that handles allocation:
psc->irq_rid = 0;
psc->irq = bus_alloc_resource_any(dev, SYS_RES_IRQ, &psc->irq_rid,
RF_ACTIVE | RF_SHAREABLE);
if (psc->irq == NULL) {
device_printf(dev, "could not allocate interrupt resource\n");
return ENXIO;
}
I was following Colin's tip (http://dev.haiku-os.org/ticket/5511),
and also found something here:
//www.freelists.org/post/haiku-bugs/Haiku-6753-KDL-after-bootup,14
So i added the following line without any luck (after the section above):
psc->irq->r_bushandle = 0x07;
The driver compiled but I don't think this would help me as I'm getting the
error from bus_alloc_resource_any,
so psc->irq will be NULL.
(Let me note please that my knowledge of driver hacking is very limited;)
I appreciate any help, thanks in advance:)
Peter
