As expected, there is another version of the cmdline patch for Kernel 4.18-rc1 – this time from Linus himself.. at  http://lkml.iu.edu/hypermail/linux/kernel/1806.2/03011.html I have applied this, and – as with the previous version –  VMware now behaves correctly.. I should mention that is is not a good idea to try to copy/paste patches from a website newsgroup listing, … Continue reading →

Fedora – F28 Annoyances, and Workarounds..

Adventures With Linux ™ Posted on June 1, 2018 by RGJune 1, 2018

Running Fedora 28 on the test system, I have encountered the following issues with various applications, and found substitute rpm workarounds..  Usually, these can be installed by downloading them ,and then using # rpm -Uvh……… –force.. Grub-customizer still crashes, but the F27 version works ( grub-customizer-5.0.6-6.fc27.x86_64 ) Wine crashes with some windows apps, and the workaround is … Continue reading →

GCC – Update to 8.1.1 – Still Gives Kernel Compile Warnings..

Adventures With Linux ™ Posted on May 7, 2018 by RGMay 7, 2018

Fedora 28 has GCC 8.1.1 available (currently in ‘updates-testing‘ repo), and I tested this with Kernel 4.17-rc4, to see if there was any improvement in the horde of warnings generated with 8.0.1. In short, there is no real difference: ……………………………… CC security/keys/request_key.o arch/x86/kvm/lapic.o: warning: objtool: kvm_lapic_reg_read()+0x126: sibling call from callable instruction with modified stack frame arch/x86/kvm/lapic.o: warning: … Continue reading →
