I applied the patch to 2.1.132 (it needed some help, but it seems to be ok). I wanted to boot from my raid0-device (created with raidtools 0.42pre3). This used to work fine till 2.1.123. Till then I get a oops ( which I mentioned on this list a couple of times). So now I applied the patch to see if it helped. It did change something: I do not get a oops but a kernel-panic, saying that the VFS could not be mounted, after the message "Bad md_map in ll_rw_block". Do I need to upgrade my array so it can be read with newer kernels? This leads to my econd problem: compiling the new raidtools (0.90) I get a compilation error: gcc -g -O2 -O2 -Wall -DMD_VERSION=\""raidtools-0.90"\" -g -c mkpv.c mkpv.c: In function `mkpv': mkpv.c:153: `BLKGETSIZE' undeclared (first use in this function) mkpv.c:153: (Each undeclared identifier is reported only once mkpv.c:153: for each function it appears in.) make: *** [mkpv.o] Error 1 I did not look into that; I need to go to bed. Could you guys help me, please? I am not on this list; please cc to me.
