But if we really do not keep some free space as default, many box will become a brick. (In fact, I just fixed a bricked dell xps 8500 last week. 5kb is not enough for dell xps...) So maybe the better way is: we check the size of nvram and decide how many space we retain. isimatu.yasuaki-+CUm20s59erQFUHtdCDX3A@public.gmane.org writes: > Hi Matt, > > I uses FUJITSU's x86 box. > This does not become bricked even if I use all efi variable storage. > Thus I want a way to not need to specify efi_no_storage_paranoia > parameter. > > Thanks, > Yasuaki Ishimatsu > > > (2013/11/08 23:34), Matt Fleming wrote: >> On Fri, 08 Nov, at 07:32:51PM, Yasuaki Ishimatsu wrote: >>>> Everything started with an issue that killed Samsung laptops: >>>> http://mjg59.dreamwidth.org/22855.html >>>> >>>> Later it was found that if you write too much into UEFI variables many >>>> UEFI implementations will do bad things. >>> >>> Thanks for the information. >>> I will read it. >> >> Out of curiosity, what hardware are you using? >> > > > -- > To unsubscribe from this list: send the line "unsubscribe linux-efi" in > the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org > More majordomo info at http://vger.kernel.org/majordomo-info.html -- Best, Madper Xie.
