[Bug 403455] Re: Intel 5300 wifi dies randomly

[dvhart]

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. Consider calling Lenovo.
