[-- Attachment #1 --] Warner, better sit down for this. I have a solution to the hangs-on-eject, but I don't understand why this should fix it. I've peppered pcic_pci_intr() with device_printf statements, to see if I could figure out where exactly the hangs happen. Funny enough, the noisy debug kernel didn't hang anymore! I've since narrowed it down to one device_printf statement, which seems to make all the difference: --- pcic_pci.c.WARNER Wed Sep 12 20:12:03 2001 +++ pcic_pci.c Wed Sep 12 20:14:03 2001 @@ -951,6 +951,7 @@ * in the CD change. */ sp->getb(sp, PCIC_STAT_CHG); + device_printf(sc->dev, "bingo!\n"); } /* Why this would help, I don't know (looks like a weird timing-related bug). The fix is also a bit noisy for a production machine :-) But maybe this'll give you a clue to really fix it. (The patch above is against the latest pcic_pci.c-patch you sent out.)
