Subject2.6.38-rc3 regression on parisc: segfaults
I have been testing devel kernels on SMP L1000 successfully until 
2.6.38-rc2-00324-g70d1f36 included. The testing means booting the new
kernel and running aptitude to update to current debian unstable.

Now I tried 2.6.38-rc3 and got a crash from aptitude on 2 out of 2
tries. Maybe aptitude was broken inbetween but it looks like a kernel
bug. Retried 2.6.38-rc2-00324-g70d1f36 and that seemed to work fine so
it's more likely a kernel problem.

What additional information can I provide?
