| 2 | Subject: [PATCH] disable catas_reset by default to avoid problems with EEH | |
| 3 | References: bnc#456389 | |
| 4 | ||
| 5 | PPC machines with EEH and Mellanox ib/net cards with catastrophic error | |
| 6 | recovery that encounter a PCI bus error can crash and become | |
| 7 | unresponsive. | |
| 8 | ||
| 9 | Disable the card reset to avoid this. | |
| 10 | ||
| 11 | NOTE: an upstream fix will come later once IBM can review a couple of | |
| 12 | approaches I suggested since this fix is brute force. This driver didn't have | |
| 13 | this reset on error feature in SLES10 so it isn't a feature removal. | |
