Hi, Should I file a bug report? Also, searching through bugzilla, ide_info is definately not in FC2 as well as FC3-test. ( i don't think I'm gonna worry about it though) Description of Problem: Kernel will hard_hang after subsequent insertion/mounting/unmounting/re-insert/re-mount/re-unmount of a CF card into a PCMCIA adapter. Only seen on high capacity CF Card(512MB, not seen on 64MB, 32Mb and 16MB card) Network connectivity is also lost. This is seen in both the 2.6.7(kernel.org) and the FC2 2.6.6-1.435 kernels Issue is not seen under RH9 system running 2.6.3 kernel. Tested and verified System Info Distro : FC2/RH9 Kerne : 2.6.6-1.435, 2.6.7, 2.6.3(RH9) Laptop : Dell D600 pcmcia-cs-3.2.7-1.5.i386.rpm kernel options root=/dev/hda9 resume=/dev/hda5 ro CF Card Tested product info: "SanDisk", "SDP", "5/3 0.6" (problematic 512MB) manfid: 0x0045, 0x0401 function: 4 (fixed disk) product info: "SunDisk", "SDP", "5/3 0.6" (OK 32MB) manfid: 0x0045, 0x0401 function: 4 (fixed disk) product info: "64MB", " " (OK 64MB PQI) manfid: 0x0000, 0x0000 function: 4 (fixed disk) How reproducible: Always for 512mb Card. Seldom for smaller capacity. Reproducible for few Kernel versions on FC2. Not reproducible on RH9 (2.6.3 kernel) on same Laptop Steps to Reproduce 1. Insert Card 2. Mount Card 3. Unmount Card 4. Eject 5. Insert card 6. Mount Card 7. Unmount Card 8. Eject Card 9. Kernel Panic found in syslog (system still OK) 10. Insert Card (Full Kernel Hang. Reboot) Expected Result: Card should mount and unmount fine Relevent Lines from /var/log/messages ====kernel 2.6.6-1.435====== kernel: hde: SanDisk SDCFB-512, DISK drive kernel: ide2 at 0x100-0x107,0x10e irq 3 kernel: hde: max request 128KiB kernel: hde: 1000944 sectors MB) w/1KiB Cache, CHS=993/16/63 kernel: hde: hde1 kernel: ide-cs: hde: Vcc 3.3, Vpp = 0.0 cardmgr[4049]: executing: './ide start 2>&1' cardmgr[4049]: + ./ide: line /sbin/ide_info: No such file or directory kernel: hde: hde1 cardmgr[4049]: executing: './ide stop 2>&1' cardmgr[4049]: + ./ide: line /sbin/ide_info: No such file or directory cardmgr[4049]: socket 0: ATA/IDE Disk kernel: hde: SanDisk SDCFB-512, DISK drive kernel: ide2 at 0x110-0x117,0x11e irq 3 kernel: hde: max request 128KiB kernel: hde: 1000944 sectors MB) w/1KiB Cache, CHS=993/16/63 kernel: hde: hde1 kernel: ide-cs: hde: Vcc 3.3, Vpp = 0.0 cardmgr[4049]: executing: './ide start 2>&1' cardmgr[4049]: + ./ide: line /sbin/ide_info: No such file or directory kernel: hde: hde1 kernel: Unable to handle paging request at virtual address 5f6f6974 kernel: printing eip: kernel: 021e1053 kernel: *pde = 00000000 kernel: Oops: 0000 [#1] kernel: Modules linked in: yenta_socket radeon autofs4 sunrpc 3c589_cs ds pcmcia_core tg3 snd_mixer_oss snd_in tel8x0 snd_ac97_codec snd_pcm snd_timer gameport snd_mpu401_uart kernel: CPU: 0 kernel: EIP: 0060:[<021e1053>] Not tainted kernel: EFLAGS: 00010002 (2.6.6-1.435) kernel: EIP is at kernel: eax: 5f6f6970 ebx: 00000084 ecx: 09a43628 edx: 00000000 kernel: esi: 00000021 edi: 0237c090 ebp: 022de668 esp: 09d3df14 kernel: ds: 007b es: 007b ss: 0068 kernel: Process pccardd (pid: threadinfo=09d3d000 task=0b06af30) kernel: Stack: 00000000 00000246 0237c3f0 0237c238 21f75338 0237c080 021f4bd2 kernel: 0ae63974 ffffffff 00000001 00000002 21f75738 21f75738 21f757b0 213e4c2c kernel: 22b61732 21f75638 00000008 00000001 22b617df 22b68150 213e4c2c 213e4d90 kernel: Call Trace: kernel: [<021f4bd2>] ide_unregister+0x30d/0x3b2 kernel: [<22b61732>] ide_release+0x1c/0x7f kernel: [<22b617df>] ide_event+0x4a/0x8f kernel: [<22b68150>] send_event+0x35/0x4c kernel: [<22b68179>] socket_remove_drivers+0x12/0x2c kernel: [<22b6819b>] socket_shutdown+0x8/0x44 kernel: [<22b685ef>] socket_remove+0x8/0x34 kernel: [<22b68664>] socket_detect_change+0x49/0x5f kernel: [<22b68780>] pccardd+0x106/0x19d kernel: [<02115e4e>] default_wake_function+0x0/0xc kernel: [<02115e4e>] default_wake_function+0x0/0xc kernel: [<22b6867a>] pccardd+0x0/0x19d kernel: [<021041d9>] kernel_thread_helper+0x5/0xb kernel: kernel: Code: 39 70 74 07 83 38 00 89 c1 75 f2 8b 11 85 d2 17 8 -- Ow Mun Heng Fedora GNU/Linux Core 2 (Tettnang) on D600 1.4Ghz CPU kernel 2.6.7-2.jul1-interactive Neuromancer 14:28:29 up 10 min, 4 users, load average: 0.16, 0.97, 0.69
