Clean install of oracleasm on SLES 11.2 (64bit) (patched or unpatched). Configured ASM. When you do a /etc/init.d/oracleasm stop, the kernel will panic in 5 seconds after doing the command. This is very repeatable. This is on a Dell R720 server, 64 Gig of ram, all local storage. I've tried going back to SLES 10.4, and don't have this problem (but shelf life of 10.4 is getting near the end, so don't want to use 10.4).
Help! I tried opening a case with Oracle, and as expected, said contact Novell.
