not gonna lie this is driving me nuts home lab drama. Debian on my cloud instance got a kernel update and now it panics during boot:
[ 2.481214] VFS: Cannot open root device "sda2" or unknown-block(0,0): error -6

It was running for months without a hiccup. Is this hardware failing at the worst possible time, or the update?
i haven't touched the hardware in months. no new disks, no new RAM, nothing. it's just the update and a reboot. i'd like to fix this properly instead of reinstalling, cuz there's quite a bit of config on this box. what am i doing wrong??
