kernel panic se snapshoty

[Radim Kolar]

po dlouhe dobe se mne dnes poprve vytvoril v tomto pripade kernel dump
pri panicu. Je ale nejak podezrele kratky. Vsichni ostatni v mailing listech
maji mnohem delsi bt. Co delam spatne?

Podle mne by mela byt konfigurace kernelu s DEBUG=-g default. Ono to nakonec
vytvori dve verze a nainstaluje to pouze tu bez debug symbolu a i kdyby to
nainstalovalo obe, tak loader stejne defaultne bere tu normalni. Takze jediny
rozdil je tech 30 MB na rootfs.

panic: lockmgr: locking against myself

syncing disks, buffers remaining... panic: ffs_copyonwrite: recursive call
