Had the same problem by upgrading from FBSD-6.3 to FBSD-7.0 right up start. I think it got some thing to do with "device cpufreq" and shared IRQ ! I had a IRQ-storm on IRQ-10, but my iwi0 need it. well to solved the problem temporally I did compile my kernel without "devi= ce cpufreq" as I had on FBSD-6.3, but the down side is that my 1.8Ghz Laptop will only run very ver= y slow with 0.228Ghz... after that (ONLY on FBSD-7.0) at the end I just removed the other PCMCIA card (a Sierra Wireless) which u= sing IRQ-10 too, but is in no function on FreeBSD any way. after that I compiled the kernel with "device cpufreq" and I'm up o 1.8GHz = without IRQ-storm again. I know this is not a finally solution, but I think we have to wait for FBSD= -7.1 or higher to brush out all this little faults. I had a similarly problem when I was updating f= rom FBSD-5.4 to FBSD-6.0 with the iwi0 driver, lots of IRQ-storms, had some thing to do with "device= cpufreq" and ACPI that time too ! hope this will go away in future. --- Hanno --Sig_/Dg5vA0hhkE.WgI21zwGBght Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (FreeBSD) iEYEARECAAYFAkgDJ+gACgkQWblSedSb6DYIqACdFWX6P8fI63dx13XJKvpZMGxB EU0An2aNd5cXZTs0R8G4AbwZhkPLlmuT =K749 -----END PGP SIGNATURE----- --Sig_/Dg5vA0hhkE.WgI21zwGBght-- ___________________________________________________________ Yahoo!
