Hi Andy,
After apllying this patch (and 1-5) to the 2.6.32
vanilla kernel I still get lots and lots of kernel panics when
hotplugging a disk.
ps. And I posted a mvsas related bug that
causes an
instant kernel panic at boot when using 3 Marvell 6480
controllers in one machine. Any news on that?
Kind regards,
Caspar Smit
