Sure. I usually update the kernel once the corresponding linux-tools
package is available (for perf), but depending on how annoying 3.7 gets
I might update earlier this time.

So far, I've had two more hangs under 3.7, but in general it was pretty
ok. 3.8 didn't hang in the short time I tried it, but it lost the
network card pretty soon after booting, spamming the kernel log with
lots of "atl1c 0000:02:00.0: PCI-DMA: Out of IOMMU space for 1522 bytes"
(with different sizes). Google gives
<url> which indicates that
the just released kernel 3.8.4 includes a fix for that. I've also found
<url>
saying "2) PCI dma mapping errors in atl1c are not checked for and this
cause hard crashes for some users, from Xiong Huang." which seems to be
the cause of the broken network, and also might be a fix for the hangs
in 3.7.

3.8.5 ran for 33 days now without problems, so it looks fixed.
