Hi again, Ok, some people tried to help me find out why does the Aironet driver panic on reinsertion, under NEWCARD with my recent patch (see previous message and PR) however I need additional help to find the problem. I'm including the complete details on the events leading to the panic. My kernel conf is at: http://devils.maquina.com/~gabriel/MINIME Verbose kernel boot dmesgs are at: http://devils.maquina.com/~gabriel/boot.newcard Card attach messages are at: http://devils.maquina.com/~gabriel/boot.an The debug dmesg I get on NEWCARD after removing the card: pccard1: 00 CD 3b cardbus0: Detaching card: no cards to detach! pccbb_pcic_socket_disable pccbb0: pccbb_power: CARD_VCC_0V and CARD_VPP_0V [44] pccbb0: WARNING: Resource left allocated! This is a bug... (rid=0, type=3, addr=44001000) pccbb0: WARNING: Resource left allocated! This is a bug... (rid=0, type=1, addr=b) pccbb0: WARNING: Resource left allocated! This is a bug... (rid=0, type=4, addr=100) This is suspicious, however I'm not sure where's the problem. After that, after I reinsert the card I get lots of scrolling lines like this: CISTPL_NONE 00 And after that DDB takes over: Fatal trap 12: page fault while in kernel mode fault virtual address = 0xcaed8000 fault code = supervisor read, page not present instruction pointer = 0x8:0xc01672c0 stack pointer = 0x10:0xc9f43c8c frame pointer = 0x10:0xc9f43e74 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 7 (pccbb0) kernel: type 12 trap, code=0 Stopped at pccard_scan_cis+0x120: movb 0(%eax,%edx,1),%al db> trace pccard_scan_cis(c1082680,c0167e0c,c9f43e88,0,0) at pccard_scan_cis+0x120 pccard_read_cis(c1091a00) at pccard_read_cis+0xa9 pccard_attach_card(c1082680) at pccard_attach_card+0xc5 pccbb_insert(c1091c00,c9f43fa8,c1091c00,c9f43f94,c01b659d) at pccbb_insert+0x9e pccbb_event_thread(c1091c00,c9f43fa8) at pcbb_event_thread+0x37 fork_exit(c0287278,c1091c00,c9f43fa8) at fork_exit+0x2d fork_trampoline() at fork_trampoline+0x8 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
