[openib-general] SRP crashes on both 2.6 and 2.4.2x,

Fri Apr 2 13:42:53 PST 2004

Has anyone successfully brought up SRP on 2.6.4 or 2.4.2x?

With 2.4.2x kernel, modprobe srp caused kernel to hang and I have to hard
reboot (ipoib worked fine before modprobe srp)

With 2.6.4 kernel, modprobe srp never return and I got a kernel oops below;
however, ipoib still work (ping is OK)

ib_srp: module license 'unspecified' taints kernel.
