Fedora – Easier ‘Fix’ for F28 Wine..

Adventures With Linux ™ Posted on by

Wine on Fedora 28 is still broken with some windows apps, and to avoid having to individually download and then run RPM on a series of F27 wine rpms, it is possible to use dnf to do the update/replacement with the – working – Fedora 27 versions. # dnf update *wine* –releasever=27 –allowerasing –best This only works … Continue reading →

VMware – Possible Clues to Failure?

Adventures With Linux ™ Posted on by

OPINION/SPECULATION: After more tests, I am still encountering the odd behaviour of VMware (14.1.2 with vmmon patch) and Kernel 4.18-rc1, but did notice one possible clue.. Looking at the # systemctl status vmware.service output, it includes the following: Jun 18 01:02:03 rgtest vmware[5663]: Blocking file system[FAILED] I think this should not be there, as VMBlock has been … Continue reading →

VMware – Odd Behaviour with Kernel 4.18-rc1, and a Workaround?

Adventures With Linux ™ Posted on by

VMware 14.1.2 worked OK with Kernel 4.17, on my Fedora 28 test system, but after updating to 4.18-rc1 the following occurred: Modules (vmmon/vmnet) compiled OK, but – after further testing – appeared to have a runtime problem..    I applied the vmmon patches from Michal Kubeček, at https://github.com/mkubecek/vmware-host-modules/commit/3f2a6c720f68 and this also compiled cleanly. When I ran # vmware-modconfig … Continue reading →

As with 14.1.1, this version is OK with the latest Linux kernels (tested with 14.6.10 and 14.7-rc6). Robert Gadsdon.   May 22, … Continue reading →

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

Adventures With Linux ™ Posted on by

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 →
