I had similar problems with a 5300 in a ThinkPad T400 on Lucid. After trying the latest linuxwireless backports and then a 2.6.36-rc4+compat- wireless, I would see errors like:
[34400.190021] iwlagn 0000:03:00.0: Failing on timeout while stopping DMA channel 1 [0xa5a5a5a0] [34400.190021] iwlagn 0000:03:00.0: MAC is in deep sleep!. CSR_GP_CNTRL = 0x080003D8 [34400.190021] iwlagn 0000:03:00.0: MAC is in deep sleep!. CSR_GP_CNTRL = 0x080003D8 After talking with the Intel wireless developers and trying everything possible with module parameters and bios settings, this turned out to be a hardware problem. I tried my harddrive in an identical T400 and it worked.
