Hi Andrew, On Wednesday, September 07, 2005 5:53 AM, Andrew Morton forwarded: > 2.6.11-mm1: works > 2.6.11-mm4: works > 2.6.12-rc5-mm1: will not compile > 2.6.12-rc6-mm1: works > 2.6.12-mm1: will not compile megaraid driver > 2.6.12-mm2: broken > 2.6.13-mm1: broken > > 2.6.12: works > 2.6.13: works Is there any precedence rule on the kernels?. I wonder which kernel is latest in between 2.6.12 and 2.6.12-mmx. I assume 2.6.12-mmx is later than 2.6.12. I'll try to dig out further if this is true, please confirm this.
