There seems to be something broken with the 'linux-official' [1] line of kernels. I now tested a lot of kernels from various sources and these are the results:
* linux-official-3.5.0-7.lemote * linux-official-3.5.0-8.lemote : Loading the Debian wheezy initrd [2], I get a blank screen about half a minute into the installation, then the system looks frozen (maybe just the display is gone?). * linux-official master branch (abab4490cfb4b89) : Same problem as above, plus the fan is spinning very loudly (CONFIG_LOONGSON3_CPUAUTOPLUG=y is set, anything else I need for proper fan control or power management?) Also tried with the newer Debian Jessie installer initrd [5], with the same result. I think that rules out a userspace issue. I.e. linux-official looks unusable for my system :/ * ralf's linux mips branch, master (859a350909b3ee) [3] * torvald's linux branch, master (04535d273ee3e) [4] : Fan spins very loudly, but Debian installer seems to work. I get a segfault somewhere early in the installation when using the Debian Wheezy installer initrd [2], but does not seem kernel related. The Debian Jessie installer [5] works much better, so far I encountered no (unexpected) problems. Remaining questions: - What's wrong with linux-official line of kernels WRT frame buffer becoming unusable? Whatever it is, hopefully the "feature" does not get merged upstream ;) Anything else I can do to help triage/debug the problem? - How do I get proper fan control (and power management) with the more recent kernels? Ralf's and Torvald's branches lack the CONFIG_LOONGSON3_CPUAUTOPLUG option. Any workarounds? cheers, David [1] http://dev.lemote.com/cgit/linux-official.git [2] http://ftp.debian.org/debian/dists/wheezy/main/installer-mipsel/current/images/loongson-2f/netboot/initrd.gz [3] git://git.linux-mips.org/pub/scm/ralf/linux [4] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git [5] ftp://ftp.de.debian.org/debian/dists/jessie/main/installer-mipsel/current/images/loongson-2f/netboot/initrd.gz -- GnuPG public key: http://dvdkhlng.users.sourceforge.net/dk2.gpg Fingerprint: B63B 6AF2 4EEB F033 46F7 7F1D 935E 6F08 E457 205F
