URL: <http://savannah.gnu.org/bugs/?45204> Summary: EFI PXE boot fails for some firmware Project: GNU GRUB Submitted by: msalter Submitted on: Thu 28 May 2015 03:11:54 PM GMT Category: Network Severity: Major Priority: 5 - Normal Item Group: Software Error Status: None Privacy: Public Assigned to: None Originator Name: Mark Salter Originator Email: address@hidden Open/Closed: Open Discussion Lock: Any Release: Release: Git master Reproducibility: Every Time Planned Release: None _______________________________________________________ Details: The patch for bug #41731 adds an exclusive open of simple network protocol to fix a problem where firmware would compete with grub for incoming packets. This has been working for me until I tested on a platform where the firmware clears the receive filter settings when the network driver is stopped by grub's exclusive open. I used the attached patch to fix the problem by saving the original receive filter settings and restoring them after the exclusive open. _______________________________________________________ File Attachments: ------------------------------------------------------- Date: Thu 28 May 2015 03:11:54 PM GMT Name: 0001-efinet-save-and-restore-SNP-rx-filters.patch Size: 65kB By: msalter patch to save/restore efinet rx filters <http://savannah.gnu.org/bugs/download.php?file_id=34114> _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?45204> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
