Strange USB crash
After having had my previous motherboard go belly-up, I've replaced it
with a new one. The entire dmesg is attached, but here's the relevant
messages for the ohci devices:
ohci0 at pci0 dev 18 function 0: vendor 0x1002 product 0x4397 (rev. 0x00)

I've had multiple crashes for no apparent reason, under varying I/O
loads (including nothing but CPU-bound code-cracker), and the backtrace
is always the same:
panic + 0x2ba
ohci_softintr + 0x466
softint_dispatch + 0xcc
gdb says that the address ohci_softintr+0x466 is in dev/usb/ohci.c at
if (sitd->flags & OHCI_CALL_DONE)
break;
ohci_free_sitd(sc, sitd);
}
>>>> ohci_free_sitd(sc, sitd);
if (uedir == UE_DIR_IN &&
xfer->status == USBD_NORMAL_COMPLETION)
xfer->actlen = actlen;
xfer->hcpriv = NULL;
And ohci_free_sitd() is defined in the same file as
void
ohci_free_sitd(ohci_softc_t *sc, ohci_soft_itd_t *sitd)
{
int s;
DPRINTFN(10,("ohci_free_sitd: sitd=%p\n", sitd));
#ifdef DIAGNOSTIC
if (!sitd->isdone) {
panic("ohci_free_sitd: sitd=%p not done", sitd);
return;
}
/* Warn double free */
sitd->isdone = 0;
#endif
...
Yes, my kernel does have 'options DIAGNOSTIC' turned on (I don't
remember why, it's just been on forever!) so hitting that panic is
certainly possible.
My questions to the usb experts:
1) should I just rebuild without DIAGNOSTIC and ignore the error?
2) Is "something bad(tm)" going to happen later if it does double-free?
3) Is this indicative of some other underlying problem?
And if so, how would I go about finding and fixing it?
For now, I'm going to remove DIAGNOSTIC, since I really need my nfs
server to be relatively stable. :)
