All right, 3 dmesg excerpts attached... 2.6.37-rc7-vanilla.dmesg: 2.6.37-rc7 vanilla (i.e. with 84c164a34ffe67908a), crashing via-rng is registered first, b43-rng second 2.6.37-rc7-without.dmesg: 2.6.37-rc7 with 84c164a34ffe67908a reverted, not crashing b43-rng is registered first, via-rng second 2.6.37-rc7-without+modprobe.dmesg: 2.6.37-rc7 with 84c164a34ffe67908a reverted, b43 blacklisted and manually modprobed after via-rng, crashing via-rng is registered first, b43-rng second Seems like the crash shows up when b43-rng is registered second, but not when via-rng is registered second. Btw.: `cat rng_available' does also not crash when via-rng is registered second. regards Mario --=20 > As Luke Leighton said once on samba-ntdom, "now, what was that about > rebooting? that was so long ago, i had to look it up with man -k." --6WlEvdN9Dv0WHSBl Content-Type: text/plain; charset=us-ascii Content-Disposition: attachment; filename="2.6.37-rc7-vanilla.dmesg" Content-Transfer-Encoding: quoted-printable [ 2.048695] b43-pci-bridge 0000:02:00.0: PCI INT A -> GSI 28 (level, low= ) -> IRQ 28 [ 2.048713] b43-pci-bridge 0000:02:00.0: setting latency timer to 64 =2E..
