Maybe. : for what it's worth, here's the behavior i'm seeing: on my vaio : z505hs with a ricoh rl5c475 pci-cardbus bridge, polling mode works : fine with the "plug & play o/s" bios option set to "yes". when i : set that bios option to "no" (so usb works), the machine will : occasionally (but not always) hang on boot after the pccard0 probe, : with no cards inserted. i haven't tried booting with cards : inserted. when the machine boots successfully, it will always hang : on a card insertion. Odd, my always works in polling mode. I have the same bridge, but the PCG-505TS instead of the x505hs. The PnP "no" setting causes more of the devices to have interrupts assigned and routed. The "yes" setting doesn't. You are running into interrupt hell that has little to do with the actual card bus bridge and more to do with FreeBSD's inability to cope properly before -current of about BSDcon. : when a card insertion does freeze the machine, i can still drop to : ddb. once in ddb, i can "next" a lot, and eventually ddb will : disappear, the machine will be unfrozen, the freshly inserted card : will probe and attach, and everything will continue normally except : that a random process will have died on SIGTRAP. same thing on card : removal. dropping to ddb and hitting "continue" doesn't work, only : "next". this seems odd. Where are you dropping into ddb at? That would be useful information. : at this point, i've got no idea how to proceed. i'm willing to : perform experiments on request, though, if that would help... I'm not sure how much it would help. Warner To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
