Subject: [PATCH] disable catas_reset by default to avoid problems with EEH
|
|
References: bnc#456389
|
|
Patch-mainline: not yet
|
|
|
|
PPC machines with EEH and Mellanox ib/net cards with catastrophic error
|
|
recovery that encounter a PCI bus error can crash and become
|
|
unresponsive.
|
|
|
|
Disable the card reset to avoid this.
|
|
|
|
NOTE: an upstream fix will come later once IBM can review a couple of
|
|
approaches I suggested since this fix is brute force. This driver didn't have
|
|
this reset on error feature in SLES10 so it isn't a feature removal.
