Kernel Archive for 4.1 Series

Hi,

Kernel 4.2 has not been kind, have an intermittent mdadm raid crash + windows 8 iscsi non compatibility. Both are reported issues upstream and look to be fixed in 4.3 series.

I tried to go back to kernel-lts series and that has longstanding issues with bcache hangs on my system :-(

Is there a way to revert to  4.1 series kernel (which I had no issues with) easily?

Many Thanks

Re: Kernel Archive for 4.1 Series

I'm confused - the LTS kernel is a 4.1 series kernel, yet you say it doesn't work for you !?!?

Re: Kernel Archive for 4.1 Series

hmm that is strange i have not seen any bcache crashes before in the 4.1 series. I had seen a similar issue a lot in older kernels.

Checking my last boot with linux-lts it does appear to be using a 4.1 series now. It must be a new bug. I will look into it further. Thanks for pointing it out!
