Hi, same crash this morning with 2.6.16-1.2230_FC6. I'm currently trying 2.6.16-1.2232_FC6 (I noticed the related thread on the LKML, and the cfq patch of this build).
yeah, hopefully that'll fix it up. keep me posted.
I have currently an uptime of 4 days with kernel 2.6.16-1.2236_FC6, so I'd say confidently, that this bug is fixed now. Thanks!
