** Description changed: - After upgrading to 17.10 (from 16.04 with 4.4 kernel) my PCI DVB card - Terratec Cinergy DVB-1200 with SAA7146 chipset is not working anymore. - There is a kernel bug message while booting and no /dev/dvb device is - created. Tried also with newest mainline 4.14 kernel - same error. + === SRU Justification === + [Impact] + Callers vmalloc_32() expect the page is not located in highmem. + All users of vmalloc_32() have this issue, module saa7146 is one of + them. + + [Test] + saa7146 crashes at probing. The issue is fixed with the patch. + + [Fix] + Add GFP_DMA32 to GFP_VMALLOC32 flag for 32bits systems. + The patch is in stable trees, so only Artful needs this patch. + + [Regression Potential] + Low. It's a crucial fix for 32bits systems. + + === Original Bug Report === + After upgrading to 17.10 (from 16.04 with 4.4 kernel) my PCI DVB card Terratec Cinergy DVB-1200 with SAA7146 chipset is not working anymore.
