From: Lucas Kannebley Tavares Date: Mon, 9 Jan 2012 12:58:06 +0000 (-0200) Subject: jsm: Fixed EEH recovery error X-Git-Tag: v3.3-rc2~4^2~12 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=26aa38cafae0dbef3b2fe75ea487c83313c36d45;p=pandora-kernel.git jsm: Fixed EEH recovery error There was an error on the jsm driver that would cause it to be unable to recover after a second error is detected. At the first error, the device recovers properly: [72521.485691] EEH: Detected PCI bus error on device 0003:02:00.0 [72521.485695] EEH: This PCI device has failed 1 times in the last hour: ... [72532.035693] ttyn3 at MMIO 0x0 (irq = 49) is a jsm [72532.105689] jsm: Port 3 added However, at the second error, it cascades until EEH disables the device: [72631.229549] Call Trace: ... [72641.725687] jsm: Port 3 added [72641.725695] EEH: Detected PCI bus error on device 0003:02:00.0 [72641.725698] EEH: This PCI device has failed 3 times in the last hour: It was caused because the PCI state was not being saved after the first restore. Therefore, at the second recovery the PCI state would not be restored.
