Hi -current, I already posted my problem to -mobile and got some useful tips there, but I still need some advice from you, and I hope someone can take a look at my problem. I upgraded my laptop from 4.7 to 5.0 via make world. The upgrade went quite smooth, but then I recognized that suspend/resume doesn't work at all when ACPI is enabled (please see my thread at -mobile for this). So I disabled ACPI and put APM back in, since APM worked very well under 4.7. Now I can suspend and resume on the console, but if I suspend when I'm in X, the machine gets stuck in a deadlock (so I have to power cycle). Someone on -mobile suggested to switch to a different vty before suspending. Ok, I did, and suspend works, but when I resume I hit a kernel panic. The strange thing is that it doesn't dump core onto swap although I configured dumpdev and everything (and I usually get a nice core dump if the machine panics). So the only information I have so far is this: pcm0: unregister: mixer busy csa: card is Thinkpad 600X/A20/T20 panic: resource_list_alloc: resource entry is busy syncing disks, buffers remaining... panic: bwrite: buffer is not busy??? Uptime: 4m5s Dumping 255 MB <---- it says so, but it doesn't do it ata0: resetting devices ..

Rebooting... Since the current process seems to have something to do with cardbus (cbb0, cbb1), I tried to remove it from the kernel. I still got the same panic, but with "fxp0, uhci0+" as process number 20 on irq 11. I'm currently building with DDB, so maybe I can get a core dump. Any tips or suggestions are appreciated.
