Initially, I too thought it was driver-specific -- one failure case was
wdsc timeouts on an IP24 with r5k.

Replacing the r5k module with an r4k module made the problem go away.

If your IP32 is stable with some permutation of Rafal's patch, then maybe we
have our fix  My unpatched r5k IP32, before it broke, frequently went into
comas during heavy load.
