BUG? FC2 Kernel Panic with PCMCIA CF Card

[Ow Mun Heng]

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
