Installing Linux Redhat7.0/6.2 to HP's LH4(Intel NX chipset) when NetRAID- 2M(AMI MegaRAID Controller) is in the primary bus(64bit). System will reboot during Linux probing the PCI bus. HP's NetRAID-2M contains a qlogic chip which is visible to the host bus. According to the PCI trace: *************************** Linux initiates I/O read one byte wide to the Qlogic SCSI Chip in the NetRaid-2M. Qlogic is not accesible to this type of cycle (I/O read one byte wide). Linux retry the cycles three times, the last Qlogic initiate target abort(stop asserted, devsel and trdy deasserted). This is valid!. However, 180ns later Linux(not certain) resets the system. My question: Does Linux susceptible to the target abort? FYI, NetRAID-2M is 64bit adapter which is preferable to go to the 64bit PCI slots.
Does this also happen with the install-floppies (or cd) from the recently released beta?
The issue could not be reproduced in LH4 systems in AMI Labs. HP Labs have confirmed that it was behaving like my above mentioned report. I will pursue with HP with using floppy's for installation.
peterj is actually the person responsible for this driver. Peter, have you been involved in tracking this down?
