Forgot to mention: root FS is on ext4, otherwise it's a more or less default install.
Same on a Toshiba 5105-s607. This machine does not have built-in 802.11a/b/g or Bluetooth, but variations on the model do.
Reinstalled with root FS on XFS, but the bug remains, so it's probably not FS related. In addition to another comment: this laptop has a "Intel Corporation PRO/Wireless 2915ABG" mini-PCI card.
FYI: Compiled a stock 2.6.28 kernel using the kernel config file of Fedora kernel 2.6.27.9-159.fc10.i686, and the BUG is gone.
I'm seeing the same problem on a Toshiba Satellite M30.
