Hi, Since upgrading sources on RELENG_7 yesterday, my amd64 system panics right after this line in dmesg: ata4: <ATA channel 2> on atapci1 panic: resource_list_alloc: resource entry is busy This machine uses an ALi SATA controller. I haven't had any problems with this controller's support for most of the 7.x branch, but it was last broken during the 6.x branch. I see there have recently been commits in this area which may have broken ATA driver support in some subtle way. Backtrace is (w/o symbols):- ... resource_list_alloc() pci_alloc_resource() bus_alloc_resource() ata_ali_sata_allocate() ata_pcichannel_attach() device_attach() ... There are no debugging symbols at the moment as this is a production kernel. If any further information is required to resolve the bug, please let me know. thanks, BMS
