Not only install, but booting of installed system too — any GENERIC kernel panics, even new, built by hands from latest sources. > It may be the case that rtsx still works even if the card reader is > disabled in the BIOS. That's the first thing I would try out. Nope, it doesn't work (and I don't need it on this Laptop, to be honest). If SD reader is disabled in BIOS, it isn't detected at all. > If that fails then generate a kernel with rtsx as a module rather than > it being hard coded into the kernel. > > You could then re-enable the SD card reader in the BIOS and load the > module to check whether the SD card reader works or causes a panic > when the moduke is loaded.

BTW, I've got hints that it it rtsx-related only after ~40 crashes, as most of stack traces don't have rtsx in them and are very generic. Looks like rtsx mangle kernel memory and it crashes in other places/kernel threads. -- // Lev Serebryakov
