|Platform||Intel SR1625URR with MegaRAIDSAS||OS||CentOS 7.6 (1810)||OS Version||1810|
|Target Version||Fixed in Version|
|Summary||0016311: Live OS Gnome version hangs on EFI boot, sometimes changing 6 bytes on stick it is booted from|
|Description||On this particular platform the Gnome version of Live OS hangs on boot. On some occasions the file /isolinux/efiboot.img in partition 1 of the image on stick gets bytes 7272, 7273, 7292, 7293, 72B2, 72B3 altered, always all three times to the same 16-bit value.|
|Steps To Reproduce||dd the file CentOS-7-x86_64-LiveGNOME-1810.iso obtained from the CentOS website (and with SHA256 checksum checked after downloading it) onto a memory stick, specifically to /dev/sdb . Eject the stick, remove it, and reinsert it. Read back the contents of the stick to a different file using dd and compare the original file with the copy-back, finding them to be the same.|
Reboot the machine, using f6 to select Boot Options menu. Choose the EFI from USB stick option. Grub2 screen appears normally; select the suggested option of "Test this media and boot...". Initial image loads and EFI-penguins appear on screen, followed by message that i8042: No controller found. Then a long pause, followed by the usual CentOS 7 grey screen with a please-wait-circle going round and round. Then the circle stops, and it hangs for ever.
On forcing the machine to reboot using its normal disc image, and rereading the stick, sometimes the above-mentioned bytes in the image have been altered, despite the fact that this is supposed to be a read-only image on the stick. If then one attempts to reboot from the stick as before, now the machine resets itself immediately after the EFI-penguins appear.
|Additional Information||In contrast if the same stick (before those six bytes have been corrupted) is booted on an HP Pavilion laptop, it boots fine, using the EFI interface. However it hangs on shutdown.|
